Surah At-Tawba Ayahs #43 Translated in English

If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allāh is over all things competent.

If you do not aid him [i.e., the Prophet (ﷺ)] - Allāh has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he [i.e., Muḥammad (ﷺ)] said to his companion, "Do not grieve; indeed Allāh is with us." And Allāh sent down His tranquility upon him and supported him with soldiers [i.e., angels] you did not see and made the word of those who disbelieved the lowest, while the word of Allāh - that is the highest. And Allāh is Exalted in Might and Wise.

Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allāh. That is better for you, if you only knew.

Had it been a near [i.e., easy] gain and a moderate trip, they [i.e., the hypocrites] would have followed you, but distant to them was the journey. And they will swear by Allāh, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allāh knows that indeed they are liars.

Allāh has pardoned you, [O Muḥammad, but] why did you give them permission [to remain behind]? [You should not have] until it was evident to you who were truthful and you knew [who were] the liars.
