إِنَّمَا يَسۡتَـٔۡذِنُكَ ٱلَّذِينَ لَا يُؤۡمِنُونَ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَٱرۡتَابَتۡ قُلُوبُهُمۡ فَهُمۡ فِي رَيۡبِهِمۡ يَتَرَدَّدُونَ ٤٥
Only those would ask permission of you who do not believe in Allāh and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.
Translation: Saheeh International (English)
Each word's meaning and sound
Those who ask the Messenger (peace be upon him)for permission to stay behind from striving for the sake of Allah are the hypocrites who do not believe in Allah and the Day of Judgement, and whose hearts are full of doubt about the sacred path of Allah. In their doubt they waver, confused, and they are not guided to the truth.
