Which was revealed in Makkah

بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ

(In the Name of Allah, the Most Gracious, the Most Merciful.

وَاذْكُرِ اسْمَ رَبِّكَ وَتَبَتَّلْ اِلَيْهِ تَبْتِيْلًا

(And remember the name of your Lord, and devote yourself to Him with exclusive devotion… 73:8). The word tabattul, literally, means 'to cut off oneself from entire creation to focus attention solely on the Creator to detach oneself from worldly things and devote oneself exclusively and sincerely to the service of Allah' The sentence: وَاذْكُرِ اسْمَ (And remember the name of your Lord...73:8) is grammatically conjoined to the sentence: 1 (Stand at night [ for prayer ].... 73:2) which enjoins upon the Holy Prophet to perform the night-prayer, and incidentally his attention is drawn in the following verse to special devotional activities in the course of the day: اِنَّ لَكَ فِي النَّهَارِ سَبْحًا طَوِيْلًا
