Malik رضي الله عنه (May Allah be pleased with him) reported Allah's Messenger صلى الله عليه سلم (Peace be upon him) as saying: He, who brought up two girls properly till they grew up, he and I would come (together) (very closely) on the Day of Resurrection, and he interlaced his fingers (for explaining the point of nearness between him and that person).
[Sahi Muslim, Hadith no. 6695]
Narrated Aisha رضي الله عنها (May Allah be pleased with her): A lady along with her two daughters came to me asking (for some alms), but she found nothing with me except one date which I gave to her and she divided it between her two daughters, and did not eat anything herself, and then she got up and went away. Then the Prophet صلى الله عليه وسلم (Peace be upon him) came in and I informed him about this story. He said, "Whoever is put to trial by these daughters and he treats them generously (with benevolence) then these daughters will act as a shield for him from Hell-Fire."
[Sahi Bukhari, Hadith no. 1418]
Abu Saeed Khudri رضي الله عنه (May Allah be pleased with him) reported that Allah's Messenger صلى الله عليه وسلم (Peace be upon him) said, If anyone has three daughters or three sisters, or two daughters or two sisters and he looks after them well, fearing Allah in this regard then for him is paradise.
