In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Ameerul Mumineen Umar Ibnul Khattaab (radiyallaahu-anhu) said:
People were (sometimes) judged by the revealing of a Divine Inspiration during the lifetime of Allah’s Apostle but now there is no longer anymore (new revelation). Now we judge you by the deeds you practice publicly, so we will trust and favour the one who does good deeds in front of us, and we will not call him to account about what he is really doing in secret, for Allah will judge him for that; but we will not trust or believe the one who presents to us with an evil deed even if he claims that his intentions were good.” [Saheeh Bukhaari: Vol 3; Hadith Number: 2641]
Imaam Abdul-Azeez Bin Baaz (rahimahullaah) said: “Whoever manifests good, it will be accepted from him and a good suspicion is held about him. And if he manifests evil, it will held against him and an evil suspicion is held about him”.
