[Indeed, that which you are promised is coming] (101)—meaning: the Hour—[and you will not cause failure]—meaning, you are not those who cause Allah to fail, such that you could outstrip Him and He would be unable to reach you.
Surat al-An'am from verse (135) to verse (137).
﴿إِنَّمَا توعدون لآتٍ﴾ ﴿ل ١٠١﴾ يَعْنِي: السَّاعَةَ ﴿وَمَا أَنْتُمْ بِمُعْجِزِينَ﴾ بِالَّذِينَ تُعْجِزُونَ اللَّهَ، فَتَسْبِقُونَهُ حَتَّى لَا يقدر عَلَيْكُم.
