Narrated Abu Katheer, the freed slave of the Ansar, narrated:
I was with my master `Ali bin Abi Talib (رضي الله عنه) when the people of an-Nahrawan were killed, and it was as if the people were upset about their being killed. `Ali (رضي الله عنه) said: O people, the Messenger of Allah (ﷺ) told us about people who would pass out of the faith like the arrow passes through the prey, then they will never come back to it until the arrow comes back to the string of the bow. And the sign of that is that there would be a black man among them who had a deformed arm: one of his arms would be like the breast of a woman, with a nipple like the nipple on a woman`s breast, around which are seven coarse hairs. Look for him, for I think he must be among them. So they looked for him and they found him on the bank of the river, lying beneath the slain. They brought him out and ’Ali (رضي الله عنه) said: Allahu Akbar! Allah and His Messenger spoke the truth. He was holding an Arabian bow of his; he took it in his hand and started poking the man`s deformity with it and said: Allah and His Messenger spoke the truth. The people said Allahu Akbar when they saw that and they rejoiced and no longer felt upset.
Narrated It was narrated that `Ali (رضي الله عنه) said:
The Messenger of Allah (ﷺ) cursed the one who pays riba, the one who consumes it, the one who writes it down, the two who witness it, the one who marries a woman and divorces her so that she becomes permissible for her first husband, and the one for whom that is done.
Narrated I was narrated that ‘Ali (رضي الله عنه) said:
“The Muslim has the right to six acts of kindness from his fellow Muslim: he should greet him with salam when he meets him; he should say ‘Yarhamukallah (may Allah have mercy on you) when he sneezes; he should visit him when he is sick; he should respond to him when he invites him; he should attend his funeral when he dies, he should love for him what he loves for himself; and he should be sincere towards him when he is not present.`
It was narrated from Abu Ishaq from al-Harith... and he narrated a similar report with the same isnad.
Narrated Ziyad bin Abi Ziyad narrated. I heard ` Ali bin Abi Talib (رضي الله عنه) adjure the people and say:
“I adjure you by Allah, did any Muslim man hear the Messenger of Allah (ﷺ) say what he said on the day of Ghadeer Khumm? And twelve men who had been at Badr stood up and testified.
