It is necessary to have a consistent daily wird—a set portion of remembrance that anchors the heart and elevates the soul. Perseverance in dhikr is not about quantity at first, but about constancy, for it is through regular repetition that hearts are purified and stations are raised. 

Every Muslim should establish a daily routine; SubḥānAllāh 33x, Al-ḥamdu lillāh 33x, Allāhu Akbar 33x (after each prayer) – Astaghfirullāh 100x (am/pm) – ṣalawāt upon the Prophet (ﷺ) 500–300x (throughout the day) – daily Qur’an recitation, even just 10 minutes, work towards 1-2 juz (especially student of knowledge & religious teacher) – and regular repetition of Lā ilāha illAllāh. 

Begin with what you can manage, but never neglect your wird. With time and sincerity, gradually build upon it, for it is through these daily devotions that one is drawn near to Allah and preserved upon the path.
