وَعَنْ أَبِي هُرَيْرَةَ
قَالَ: جَاءَتْ فَاطِمَةُ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ تَسْأَلُهُ خَادِمًا فَقَالَ: «أَلَا أَدُلُّكِ عَلَى مَا هُوَ خَيْرٌ مِنْ خَادِمٍ؟ تُسَبِّحِينَ اللَّهَ ثَلَاثًا وَثَلَاثِينَ وَتَحْمَدِينَ اللَّهَ ثَلَاثًا وَثَلَاثِينَ وَتُكَبِّرِينَ اللَّهَ أَرْبَعًا وَثَلَاثِينَ عِنْدَ كُلِّ صَلَاةٍ وَعِنْدَ مَنَامِكِ»
When Fatima went to the Prophet (sallallahu alayhi wa sallam) and asked him for a servant, he said, “Let me guide you to something which is better than a servant. You should say ‘Glory be to God thirty-three times, ‘Praise be to God’ thirty-three times, and ‘God is most great’ thirty-four times at each time of prayer and when you go to bed.’”
