Hadith on Dhikr: Remember Allah for strength to keep working

Ali reported: Fatimah complained about blisters on her hands from working the millstone and she asked for a servant. The Prophet, peace and blessings be upon him, said, “Shall I not tell you what is better than you ask for? When both of you lay down to sleep, exalt Allah thirty-four times, glorify Allah thirty-three times, and praise Allah thirty-three times. This is better for you both than a servant.

عَنْ عَلِي أَنَّ فَاطِمَةَ اشْتَكَتْ مَا تَلْقَى مِنْ الرَّحَى فِي يَدِهَا وسألت عن خادم فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَلَا أُعَلِّمُكُمَا خَيْرًا مِمَّا سَأَلْتُمَا إِذَا أَخَذْتُمَا مَضَاجِعَكُمَا أَنْ تُكَبِّرَا اللَّهَ أَرْبَعًا وَثَلَاثِينَ وَتُسَبِّحَاهُ ثَلَاثًا وَثَلَاثِينَ وَتَحْمَدَاهُ ثَلَاثًا وَثَلَاثِينَ فَهْوَ خَيْرٌ لَكُمَا مِنْ خَادِمٍ
