حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ‏:‏ حَدَّثَنَا سَلَمَةُ قَالَ‏:‏ سَمِعْتُ أَنَسًا يَقُولُ‏:‏ أَتَتِ امْرَأَةٌ النَّبِيَّ صلى الله عليه وسلم تَشْكُو إِلَيْهِ الْحَاجَةَ، أَوْ بَعْضَ الْحَاجَةِ، فَقَالَ‏:‏ أَلاَ أَدُلُّكِ عَلَى خَيْرٍ مِنْ ذَلِكَ‏؟‏ تُهَلِّلِينَ اللَّهَ ثَلاَثِينَ عِنْدَ مَنَامِكِ، وَتُسَبِّحِينَ ثَلاَثًا وَثَلاَثِينَ، وَتَحْمَدِينَ أَرْبَعًا وَثَلاَثِينَ، فَتِلْكَ مِئَةٌ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا‏.‏

Anas reported that a woman came to the Prophet, to complain to him of a need. He said, 'Shall I show you something better than that? You should say, 'There is no god but Allah' 33 times when you go to sleep and say 'Glory be to Allah' 33 times and say 'Praise be to Allah' 34 times and then that hundred is better than his world and all that it contains.'"
