A man said: “O Messenger of Allah, the laws of Islam have become many for me; tell me something to cling to.” He ﷺ said: “Let your tongue remain moist with the remembrance of Allah.” (Tirmidhī — ṣaḥīḥ). And: “The example of one who remembers his Lord and one who does not is like the living and the dead.” (al-Bukhārī).
العربية: عن عبد الله بن بُسر رضي الله عنه أنّ رجلًا قال: يا رسول الله، إنّ شرائع الإسلام قد كثُرت عليّ، فأخبرني بشيءٍ أتشبّث به، قال: «لا يزال لسانك رَطبًا من ذكر الله». (الترمذي).
Fill the gaps of your day with dhikr — tasbīḥ, istighfār, ṣalawāt — keep your tongue busy with Allah.
