In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

The Messenger [peace and blessings of Allaah be upon him] said, “Any man whom Allaah has given authority to look after the affairs of a people and he dies whilst not looking after them [in the manner obligated by Allaah and His Messenger], he will not smell the scent of paradise”. [Saheeh Al-Bukhaari’ Number 7150]

Imaam Muhammad Ibn Saaleh Al-Uthaymeen [may Allaah have mercy upon him] said, “This does not (only) refer to the Muslim ruler, his assistant or a minister, or the elders of a people; rather it applies even to a man in his house. If he dies and did not look after his family (in the manner obligated by Allaah and His Messenger), then indeed Allaah will prevent him from smelling the scent of paradise. And those who give their families games (or means of amusement) that corrupt manners and destroy (sound) belief, then there is no doubt that they have not looked after their families (in the manner obligated by Allaah and His Messenger in this affair). And if they die whilst being upon this state, it is feared that Allaah will prevent them from smelling the scent of paradise. (1)

Imaam Abdul Azeez Bin Baaz [may Allaah have mercy upon him] said, “The sinners [i.e. those who die whilst committing sins lesser than shirk] are under the will of Allaah- if Allaah wishes, He will either punish them or forgive them straight away, or He enters them into hell for some time and paradise thereafter, just as Allaah said: [إِنَّ ٱللَّهَ لَا يَغۡفِرُ أَن يُشۡرَكَ بِهِۦ وَيَغۡفِرُ مَا دُونَ ذَٲلِكَ لِمَن يَشَآءُ‌-Verily, Allah forgives not that partners should be set up with him in worship, but He forgives except that (anything else) to whom He pleases. [Surah An-Nisaa’ Aayah 48] (2)

[Ref 2: https://www.binbaz.org.sa/noor/2527%5D
إن أهل المعاصي تحت مشيئة الله، إن شاء الله غفر لهم وأدخلهم الجنة من أول وهلة، وإن شاء عذبهم في النار على قدر معاصيهم مدة من الزمن، ثم بعد التطهير والتمحيص يخرجهم الله من النار إلى الجنة، كما قال الله -سبحانه-: إِنَّ اللَّهَ لا يَغْفِرُ أَنْ يُشْرَكَ بِهِ وَيَغْفِرُ مَا دُونَ ذَلِكَ لِمَنْ يَشَاءُ
