It is narrated from Umm Rashid that she says: I was with Umm Hani when Hazrat Ali (may Allah be pleased with him) came to her. Umm Hani invited him to eat. Hazrat Ali (may Allah be pleased with him) said: What is the matter, I do not see "Barakat" (a goat) at your place. Umm Hani said: Subhan Allah, why not! By Allah, we have Barakat. Hazrat Ali (may Allah be pleased with him) said: I meant a goat. When I went down, I met two men on the stairs. I heard one of them saying to the other: Our hands have pledged allegiance, but our hearts have not. Umm Rashid asked: Who are these? The people replied: Talha and Zubair. I heard one of them saying to the other: Our hands have pledged allegiance, but our hearts have not. Then Hazrat Ali (may Allah be pleased with him) recited this verse { فَمَنْ نَکَثَ فَإِنَّمَا یَنْکُثُ عَلَی نَفْسِہِ وَمَنْ أَوْفَی بِمَا عَاہَدَ عَلَیْہُ اللَّہَ فَسَیُؤْتِیہِ أَجْرًا عَظِیمًا }. (Whoever breaks the covenant, its burden will be upon him; and whoever fulfills the covenant he made with Allah, Allah will give him a great reward).
