And Umar bin Hamzah said: Salim narrated the hadith to us, from his father, he said:
Sometimes I would remember this saying of the poet when I looked towards the face of the Prophet ﷺ, he ﷺ would seek rain, and he ﷺ had not yet come down from the pulpit, until every waterspout was flowing with force and noise, and that verse was this: The fair-skinned one, through whose means rain is sought from the clouds, Who is the support of orphans and the guardian of widows. (And this saying is that of Hazrat Abu Talib.)
وَقَالَ عُمَرُ بْنُ حَمْزَةَ، حَدَّثَنَا سَالِمٌ، عَنْ أَبِيهِ
رُبَّمَا ذَكَرْتُ قَوْلَ الشَّاعِرِ، وَأَنَا أَنْظُرُ إِلَى وَجْهِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَسْتسقي، فَمَا يَنْزِلُ حَتَّى وَأَبْيَضَ يُسْتَسْقَى الغَمَامُ بِوَجْهِهِ ... ثِمَالُ اليَتَامَى عِصْمَةٌ لِلْأَرَامِلِ
