"يَا حَسَّانُ: أَجِبْ عَنْ رَسُولِ الله، اللَّهُمَّ أيِّدْهُ بِرُوحِ الْقُدُسِ".
I asked Abu Huraira "By Allah! Tell me the truth whether you heard the Prophet ﷺ saying, 'O Hassan! Reply on behalf of Messenger of Allah ﷺ. O Allah! Help him with the Holy Spirit." Abu Huraira said, "Yes . "
سَمِعْتَ النَّبِيَّ ﷺ يَقُولُ يَا حَسَّانُ أَجِبْ عَنْ رَسُولِ اللَّهِ ﷺ اللَّهُمَّ أَيِّدْهُ بِرُوحِ الْقُدُسِ قَالَ أَبُو هُرَيْرَةَ نَعَمْ
that he heard Hassan bin Thabit Al-Ansari asking the witness of Abu Huraira, saying, "O Abu- Huraira! I beseech you by Allah (to tell me). Did you hear Messenger of Allah ﷺ saying' 'O Hassan ! Reply on behalf of Messenger of Allah ﷺ. O Allah ! Support him (Hassan) with the Holy Spirit (Gabriel).'?" Abu Huraira said, "Yes."
سَمِعْتَ رَسُولَ اللَّهِ ﷺ يَقُولُ يَا حَسَّانُ أَجِبْ عَنْ رَسُولِ اللَّهِ اللَّهُمَّ أَيِّدْهُ بِرُوحِ الْقُدُسِ قَالَ أَبُو هُرَيْرَةَ نَعَمْ
I adjure you by Allah if you had not heard Allah's Apostle ﷺ saying: Hassin, give a reply on behalf of the Messenger of Allah. O Allah, help him with Ruh-ul-Qudus. Abu Huraira said: Yes, it is so.
سَمِعْتَ النَّبِيَّ ﷺ يَقُولُ يَا حَسَّانُ أَجِبْ عَنْ رَسُولِ اللَّهِ ﷺ اللَّهُمَّ أَيِّدْهُ بِرُوحِ الْقُدُسِ قَالَ أَبُو هُرَيْرَةَ نَعَمْ
ذِكْرُ الْبَيَانِ بِأَنَّ كَوْنَ جِبْرِيلَ عَلَيْهِ السَّلَامُ مَعَ حَسَّانِ بْنِ ثَابِتٍ مَا دَامَ يُهَاجِي الْمُشْرِكِينَ، إِنَّمَا كَانَ ذَلِكَ بِدُعَاءِ الْمُصْطَفَى ﷺ
I adjure you by Allah if you had not heard Allah's Apostle ﷺ saying: Hassin, give a reply on behalf of the Messenger of Allah. O Allah, help him with Ruh-ul-Qudus. Abu Huraira said: Yes, it is so. (Using translation from Muslim 2485c)
سَمِعْتَ رَسُولَ اللَّهِ ﷺ يَقُولُ «أَجِبْ عَنِّي اللَّهُمَّ أَيِّدْهُ بِرُوحِ الْقُدُسِ» قَالَ نَعَمْ
