سنن النسائي

Suhaib narrated that he heard Abu Hurairah and Abu Sa'eed say: "The Messenger of Allah (ﷺ) addressed us one day and said: 'By the One in Whose hand is my sould' three times then he lowered his head, and each of us lowered his head, weeping, and we did not know what he had sworn that oath about. Then he raised his head with joy on his face, and that was dearer to us than red camels. Then he said: 'There is no one who offers the five (daily) prayers, fasts Ramadan, pays Zakah and avoid the seven major sins, but the gates of Paradise will be opened to him, and it will be said to him: Enter in peace."'
