Narrated 'Abdullah bin Yazid Al-Ansari that he went out with Al-Bara' bin 'Azib, and Zaid bin Arqam and invoked for rain. He ('Abdullah bin Yazid) stood up but not on a pulpit and invoked Allah for rain and then offered two Rak'a prayers with loud recitation without pronouncing Adhan or Iqama. Abu Ishaq said that 'Adbullah bin Yazid had seen the Prophet ﷺ (doing the same)
خَرَجَ عَبْدُ اللَّهِ بْنُ يَزِيدَ الأَنْصَارِيُّ وَخَرَجَ مَعَهُ الْبَرَاءُ بْنُ عَازِبٍ وَزَيْدُ بْنُ أَرْقَمَ ؓ فَاسْتَسْقَى فَقَامَ بِهِمْ عَلَى رِجْلَيْهِ عَلَى غَيْرِ مِنْبَرٍ فَاسْتَغْفَرَ ثُمَّ صَلَّى رَكْعَتَيْنِ يَجْهَرُ بِالْقِرَاءَةِ وَلَمْ يُؤَذِّنْ وَلَمْ يُقِمْ
