“Those, who have disbelieved, let them not think, that it is better for them that We grant them respite. We grant them respite, so that they may add more sin to themselves and for them there is a disgraceful punishment.” [Al Imran 3:178]

ولا يحسبن الذين كفروا إنما نملي لهم خير لأنفسهم إنما نملي لهم ليزدادوا اثما ولهم عذاب مهين

Muhammad ibn Muslim reported that he asked Imam Al-Baqir (a.): “Tell me about the disbeliever. Is death better for him or is life?” He said: “Death is better for the believer as well as for the disbeliever.” I said: “Why?” He said: “Because God says: ﴾What is with God is better for the pious.﴿ (3:198) And He says: ﴾Let not those who disbelieve think that it is better for them that We grant them respite. We grant them respite, so that they may add more sin to themselves and for them there is a disgraceful punishment.﴿” (3:178) Yunus reported asking him: “Did the Messenger of God (s.) marry his daughter to so-and-so (Uthman)?” He said: “Yes.” I said: “How did he also marry the other one to him?” He said: “He did that. Therefore God revealed: ﴾Let not those who disbelieve think that it is better for them that We grant them respite. We grant them respite so that they may add more sin to themselves and for them there is a disgraceful punishment.﴿” (3:178) [Tafsir-ul-Ayyashi, Volume 1, page 206 – 207]

عن محمد بن مسلم عن أبي جعفر عليه السلام قال: قلت له: أخبرني عن الكافر الموت خير له أم الحياة؟ فقال: الموت خير للمؤمن والكافر، قلت: ولم؟ قال: لان الله يقول: وما عند الله خير للأبرار ويقول: ولا يحسبن الذين كفروا إنما نملي لهم خير لأنفسهم إنما نملي لهم ليزدادوا اثما ولهم عذاب مهين وعن يونس رفعه قال: قلت له: زوج رسول الله صلى الله عليه وآله ابنته فلانا (عثمان) قال نعم، قلت: فكيف زوجه الأخرى قال: قد فعل فأنزل الله ولا يحسبن الذين كفروا إنما نملي لهم خير لأنفسهم إلى عذاب مهين

Muhammad Ibn Hasan At-Tusi writes: “He (the Prophet) married his two daughters, Ruqayyah and Umm Kulthum, to Uthman. When the second daughter died, he said: ﴾If I had a third, I would marry her to him as well.﴿” [Al-Mabsut, Volume 4, page 159]

قال الشيخ محمد بن الحسن الطوسي: وزوج (النبي صلى الله عليه وآله) بنتيه رقية وأم كلثوم عثمان، لما ماتت الثانية قال: لو كانت ثالثة لزوجناه إياها
