Sahih al-Bukhari 1008, 1009
Narrated `Abdullah bin Dinar:
My father said, "I heard Ibn `Umar reciting the poetic verses of Abu Talib: And a white (person) (i.e. 
the Prophet) who is requested to pray for rain and who takes care of the orphans and is the guardian of 
widows." Salim's father (Ibn `Umar) said, "The following poetic verse occurred to my mind while I 
was looking at the face of the Prophet (p.b.u.h) while he was praying for rain. He did not get down till 
the rain water flowed profusely from every roof-gutter: And a white (person) who is requested to pray 
for rain and who takes care of the orphans and is the guardian of widows . . . And these were the 
words of Abu Talib."
حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا أَبُو قُتَيْبَةَ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ ابْنَ عُمَرَ، يَتَمَثَّلُ بِشِعْرِ أَبِي طَالِبٍ وَأَبْيَضَ يُسْتَسْقَى الْغَمَامُ بِوَجْهِهِ ثِمَالُ الْيَتَامَى عِصْمَةٌ لِلأَرَامِلِ وَقَالَ عُمَرُ بْنُ حَمْزَةَ حَدَّثَنَا سَالِمٌ، عَنْ أَبِيهِ، رُبَّمَا ذَكَرْتُ قَوْلَ الشَّاعِرِ وَأَنَا أَنْظُرُ، إِلَى وَجْهِ النَّبِيِّ صلى الله عليه وسلم يَسْتَسْقِي، فَمَا يَنْزِلُ حَتَّى يَجِيشَ كُلُّ مِيزَابٍ‏.‏ وَأَبْيَضَ يُسْتَسْقَى الْغَمَامُ بِوَجْهِهِ ثِمَالَ الْيَتَامَى عِصْمَةً لِلأَرَامِلِ وَهْوَ قَوْلُ أَبِي طَالِبٍ‏.‏
