Mishkat al-Masabih 9 Supplications كتاب الدعوات 20

وَعَن سَلْمَانَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ رَبَّكُمْ حَيِيٌّ كَرِيمٌ يَسْتَحْيِي مِنْ عَبْدِهِ إِذَا رَفَعَ يَدَيْهِ إِلَيْهِ أَنْ يَرُدَّهُمَا صِفْرًا» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَالْبَيْهَقِيُّ فِي الدَّعوات الْكَبِير

Salman reported God’s messenger as saying, “Your Lord is munificent and generous, and is ashamed to turn away empty the hands of a servant when he raises them to Him .” Tirmidhi, Abu Dawud and Baihaqi, in [Kitab] ad-Da’awat al-kabir , transmitted it.
