Talhah bin Ubaidullah (may Allah be pleased with him) narrated: I heard the Messenger of Allah (peace and blessings be upon him) delivering a sermon on the pulpit: Beware, O people! Seek forgiveness from your Lord for your sins before death comes, and hasten to do righteous deeds before you become preoccupied. Strengthen the relationship between you and your Lord with abundant remembrance and frequent charity, both secretly and openly. Adopt indifference towards the world, earn reward, help others, and know! Indeed, Allah the Exalted has made Friday obligatory upon you, from the place where I am standing, on this day of mine, in this month of mine, in this year of mine, until the Day of Resurrection. Whoever abandons it during my lifetime or after my death, while he has an Imam, Allah will not gather his scattered affairs, Allah will not bless his matters, none of his good deeds will be accepted, neither his fasting nor his prayer. Beware! No woman should lead a man, no Bedouin should lead a Muhajir, and no wicked person should lead a believer in prayer, except if he is compelled by a ruler whose sword and whip he fears.
