وَعَنْ مُعَاذِ بْنِ جَبَلٍ رضى الله عنه
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«مَا عَمِلَ ابْنُ آدَمَ عَمَلاً أَنْجَى لَهُ مِنْ عَذَابِ اَللَّهِ مِنْ ذِكْرِ اَللَّهِ»
“A man does nothing to rescue himself from Allah’s punishment better than remembering Allah.” Related by Ibn Abi Shaibah and At-Tabarani with a good chain of narrators.
