Mustadrak al-Hakim 1219

ʿAlī b. al-Ḥusayn al-Ṣaffār> Hārūn b. Isḥāq al-Hamdānī > Wakīʿ > Sufyān > Hishām b. Isḥāq b. ʿAbdullāh b. Kinānah from his father > Arsalanī Amīr from al-Umarāʾ > Ibn ʿAbbās Asʾaluh

His father said: "One of the governors sent me to Ibn Abbas to ask him about the prayer for rain. He said: 'What kept him from asking me? The Messenger of Allah ﷺ went out humbly, (dressed) in a state of humility, submissiveness and beseeching, and he prayed two rak'ahs as in the Eid prayer, but he did not deliver a Khutbah like this Khutbah of yours.'"

وَأَخْبَرْنَاهُ أَبُو عَلِيٍّ الْحُسَيْنُ بْنُ عَلِيٍّ الْحَافِظُ ثنا عَلِيُّ بْنُ الْحُسَيْنِ الصَّفَّارُ بِبَغْدَادَ ثنا هَارُونُ بْنُ إِسْحَاقَ الْهَمْدَانِيُّ ثنا وَكِيعٌ ثنا سُفْيَانُ عَنْ هِشَامِ بْنِ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ كِنَانَةَ عَنْ أَبِيهِ قَالَ أَرْسَلَنِي أَمِيرٌ مِنَ الْأُمَرَاءِ إِلَى ابْنِ عَبَّاسٍ أَسْأَلُهُ عَنِ الصَّلَاةِ فِي الِاسْتِسْقَاءِ فَقَالَ ابْنُ عَبَّاسٍ مَا مَنَعَهُ

أَنْ يَسْأَلَنِي «خَرَجَ رَسُولُ اللَّهِ ﷺ مُتَوَاضِعًا مُتَبَذِّلًا مُتَخَشِّعًا مُتَضَرِّعًا مُتَرَسِّلًا فَصَلَّى رَكْعَتَيْنِ كَمَا يُصَلِّي فِي الْعِيدِ وَلَمْ يَخْطُبْ خُطْبَتَكُمْ»
