عن أنس بن مالك قال قال رسول الله ﷺ ثلاثة من أصل الايمان الكف عمن قال لا إله إلا الله ولا تكفِّره بذنب ولا تخرجه من الاسلام بعمل والجهاد ماضٍ منذ بعثني الله إلى أن يقاتل آخر أمتي الدجال لا يُبطله جور جائر ولا عدل عادل والايمان بالأقدار
سنن ابي داود كتاب الجهاد
From Anas ibn Malik who said: The Messenger of Allah (SAW) said: Three things lie at the root of belief: To desist from someone who says “There is no god but Allah”; that you do not accuse him of disbelief for any sin; and that you do not force him out of Islam for anything he does. And there will be jihad from the time Allah has sent me forth until the last of my ummah fight the Impostor Messiah [Dajjal]. No tyrant’s tyranny nor any just man’s justice will annul this; belief is by things preordained.
