Salman (RAA) narrated that the Messenger of Allah (ﷺ) said:

“Your Rabb (Lord of the Universe) is Modest and Generous, and would never turn the hands of a slave without gain when he raises them to Him (in supplication).” Related by the four lmams except An-Nasa’i. Al-Hakim graded it as Sahih.

وَعَنْ سَلْمَانَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ إِنَّ رَبَّكُمْ حَيِيٌّ كَرِيمٌ, يَسْتَحِي مِنْ عَبْدِهِ إِذَا رَفَعَ إِلَيْهِ يَدَيْهِ أَنْ يَرُدَّهُمَا صِفَرًا } أَخْرَجَهُ اَلْأَرْبَعَةُ إِلَّا النَّسَائِيَّ, وَصَحَّحَهُ اَلْحَاكِمُ .‏ [1]‏ .‏
