TIRMIDHI 3375:
from ʿAbdullāh b. Busr —
A man said: “O Messenger of Allah ﷺ, indeed, the legislated acts of Islam have become too much for me, so inform me of a thing that I should stick to.” He ﷺ said: “Let not your tongue cease to be moist with the remembrance of Allah.”
الترمذي ٣٣٧٥:
عن عبد الله بن بسر —
أَنَّ رَجُلاً قَالَ: يَا رَسُولَ اللَّهِ، إِنَّ شَرَائِعَ الإِسْلاَمِ قَدْ كَثُرَتْ عَلَىَّ، فَأَخْبِرْنِي بِشَيْءٍ أَتَشَبَّثُ بِهِ. قَالَ: «لاَ يَزَالُ لِسَانُكَ رَطْبًا مِنْ ذِكْرِ اللَّهِ».
