Sunan Ibn Majah Hadith 1081

“The Messenger of Allah (ﷺ) delivered a sermon to us and said: ‘O people! Repent to Allah before you die. Hasten to do good deeds before you become preoccupied (because of sickness and old age). Uphold the relationship that exists between you and your Lord by remembering Him a great deal and by giving a great deal of charity in secret and openly. (Then) you will be granted provision and Divine support, and your condition will improve. Know that Allah has enjoined Friday upon you in this place of mine, on this day, in this month, in this year, until the Day of Resurrection. Whoever abandons it, whether during my lifetime or after I am gone, whether he has a just or an unjust ruler, whether he takes it lightly or denies (that it is obligatory), may Allah cause him to lose all sense of tranquility and contentment, and may He not bless him in his affairs. Indeed, his prayer will not be valid, his Zakat will not be valid, his Hajj will not be valid, his fasting will not be valid, and his righteous deeds will not be accepted, until he repents. Whoever repents, Allah will accept his repentance. No woman should be appointed as Imam over a man, no Bedouin should be appointed as Imam over a Muhajir, no immoral person should be appointed as Imam over a (true) believer, unless that is forced upon him and he fears his sword or whip.’”
