In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Imaam Abdul Azeez Bin Baaz [may Allaah have mercy upon him] stated:
There is no doubt that the Israa Wal Miraaj are from Allaah’s Great Signs, which is shows the truthfulness of His Messenger Muhammad [peace and blessings of Alaah be upon him], the greatness of his status in the Sight of Allaah [The Mighty and Exalted], as well as evidence of Allaah’s Magnificent Power and His Exaltation above His Creation [Mankind, Jinn etc]. Allaah [Glorified be He and free is He from all imperfections] said:
سُبْحَانَ الَّذِي أَسْرَى بِعَبْدِهِ لَيْلًا مِنَ الْمَسْجِدِ الْحَرَامِ إِلَى الْمَسْجِدِ الْأَقْصَى الَّذِي بَارَكْنَا حَوْلَهُ لِنُرِيَهُ مِنْ آيَاتِنَا إِنَّه هُوَ السَّمِيعُ الْبَصِيرُ
Glorified (and Exalted) be He (Allah) [above all that (evil) they associate with Him], Who took His slave (Muhammad ) for a journey by night from Al-Masjid-al-Haram (at Makkah) to the farthest mosque (in Jerusalem), the neighbourhood whereof We have blessed, in order that We might show him (Muhammad) of Our Ayat (proofs, evidences, lessons, signs, etc.). Verily, He is the All-Hearer, the All-Seer. [Surah Al-Israa. Verse 1]
It has been transmitted by way of Tawaatur -[i.e. an authentic narration transmitted by numerous narrators to the extent that such narrators cannot all agree on a lie]- from Allaah’s Messenger [peace and blessings of Allaah be upon him] that he was taken up to the heavens and its gates were opened for him until he went past the Seventh Heaven. Then his Lord [Allaah (Glorified be He and free is He from all imperfections)] spoke to him regarding what He willed and obligated the five daily prayers on him. Allaah [Glorified be He and free is He from all imperfections] obligated fifty daily prayers on him at first, but our Prophet [peace and blessings of Allaah be upon him] did not cease going back to Allaah and asking Him to reduce the obligation, until Allaah made it five – five obligatory prayers but their reward is equal to fifty. That is because (one) good deed carries ten rewards. Therefore, all praise and thanks be to Allaah for all His blessings [i.e. all the blessings bestowed on His servants].
This night -in which the Israa Wal Miraaj took place- has not been transmitted in the authentic narrations that it took place-specifically-in the month of Rajab or other than it. All that has been narrated about the specific (month in which) it took place is not transmitted from the Prophet [peace and blessings of Allaah be upon him] with authentic chains of transmission according to the scholars of Hadeeth. And with Allah is Perfect Wisdom [free from all weaknesses, shortcomings, deficiencies, faults] as to why He made the people forget [the specific night the Israa and Miraaj took place].
And even if the specific night it took place was established, then still it would neither be permissible for the Muslims to specify any act of worship in relation to it nor celebrate it. That is because the Prophet [peace and blessings of Allaah be upon him] and his companions [may Allaah be pleased with them] neither celebrated it nor did they carry out any specific acts of worship on such a night. Had it been that celebrating it is legislated (in the religion), the Messenger [peace and blessings of Allaah be upon him] would have made it known to the Ummah-either by way of speech or action. And if anything was practiced, then it would have been known and widely known and his companions would have transmitted it to us, for indeed, they have transmitted – from our Prophet- everything that is needed by the Ummah. They did not neglect anything in the religion; rather they were foremost in practicing every righteous act. Therefore, if celebrating on this night was legislated (in Islaam), they would have preceded us in such an act. The Prophet is (was) the most sincere adviser to the people [i.e. in both their religious and worldly affairs], conveyed the message perfectly and fulfilled the trust [which Allaah entrusted on him]. If exalting this night and celebrating it was something (legislated) in the religion, then neither would the Prophet [peace and blessings of Allaah be upon him] have neglected nor concealed it.
Therefore, when it [is it the case that nothing has been transmitted from the Prophet’s speech or actions, and from his companions] about this, then one knows that celebrating and exalting this night has nothing to do with Islaam, for indeed Allaah has perfected the religion for this Ummah, completed His favour upon them and censured the one who legislates in the religion that which is not part of it. Allaah [Glorified and Exalted be He] said: [الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلامَ دِينًا – This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion. [Surah Al-Maa’idah. Verse 3]
أَمْ لَهُمْ شُرَكَاءُ شَرَعُوا لَهُمْ مِنَ الدِّينِ مَا لَمْ يَأْذَنْ بِهِ اللَّهُ وَلَوْلا كَلِمَةُ الْفَصْلِ لَقُضِيَ بَيْنَهُمْ وَإِنَّ الظَّالِمِينَ لَهُمْ عَذَابٌ أَلِيمٌ
Or have they partners with Allah (false gods), who have instituted for them a religion which Allah has not allowed. And had it not been for a decisive Word (gone forth already), the matter would have been judged between them. And verily, for the Zalimun (polytheists and wrong-doers), there is a painful torment. [Surah Ash-Shura. Verse 21]
And it has been transmitted from Allaah’s Messenger in the authentic narrations that he warned against innovations in religion and stated explicitly that it is deviation in order to warn the Ummah about the great danger of religious innovations and to keep them away from acting on it. It was transmitted from Aa’isha [may Allaah be pleased with her] that the Prophet [peace and blessings of Allaah be upon him] said: [من أحدث في أمرنا هذا ما ليس منه فهو رد – Whoever innovates something in this affair of ours [i.e. the religion of Islaam], it will be rejected].[Saheeh Al-Bukhaari 2697]
[من عمل عملاً ليس عليه أمرنا فهو رد – Whoever performs (an act of worship) which not in accordance with our affair [i.e. the religion of Islaam], it will be rejected]. [Saheeh Muslim 1718]
The Messenger [peace and blessings of Allaah be upon him] said:
أُوصِيكُمْ بِتَقْوَى اللَّهِ وَالسَّمْعِ وَالطَّاعَةِ وَإِنْ عَبْدًا حَبَشِيًّا فَإِنَّهُ مَنْ يَعِشْ مِنْكُمْ بَعْدِي فَسَيَرَى اخْتِلَافًا كَثِيرًا فَعَلَيْكُمْ بِسُنَّتِي وَسُنَّةِ الْخُلَفَاءِ الْمَهْدِيِّينَ الرَّاشِدِينَ تَمَسَّكُوا بِهَا وَعَضُّوا عَلَيْهَا بِالنَّوَاجِذِ وَإِيَّاكُمْ وَمُحْدَثَاتِ الْأُمُورِ فَإِنَّ كُلَّ مُحْدَثَةٍ بِدْعَةٌ وَكُلَّ بِدْعَةٍ ضَلَالَةٌ
I command you to fear Allaah and to listen and obey [the Muslim ruler in what is good] even if a slave is a leader over you. Certainly, the one who will live among you will see lots of differences, so adhere to my Sunnah and the Sunnah of the right-guided Khulafaa [i.e. Abu Bakr, Umar, Uthmaan and Ali]. Bite onto that with your molar teeth [i.e. adhere firmly to it] and beware of the newly-invented matters in the religion, because every newly invented affair in the religion is a Bidah [religious innovation] and every bidah is misguidance. [Sunan Abu Dawud 4607]
The narrations that convey the meaning of this affair are many. And it has been transmitted from the companions of Allaah’s Messenger and the pious predecessors [i.e. the first three generations of Islaam] after them that they warned against religious innovations and [gave advice to the people in order to make them fearful of practicing religious innovations]. That is because such practices are additions [i.e. acts that are not legislated by Allaah and His Messenger] and [practicing them] is tantamount to legislating something in the religion, which Allaah has not ordained. It is tantamount to belittling the religion of Islam and accusing it [of imperfection] after it was perfected.
And when it is the case that Allah has obligated on Muslims to give advice to another and explain what He has legislated for them in the Religion, and forbade one from concealing knowledge, I saw that I should notify (or warn) my Muslim brothers about this religious innovation, which has spread to many regions, to the extent that some people think that it is something related to the religion.
