(Mu'amin) 40 : 51
إِنَّا لَنَنْصُرُ رُسُلَنَا وَالَّذِينَ آمَنُوا فِي الْحَيَاةِ الدُّنْيَا وَيَوْمَ يَقُومُ الْأَشْهَادُ

Indeed We will help the Messengers and those who believed in this worldly life and on the Day witnesses will stand up.

It is to be remembered that even though many Prophets have been killed, no Messenger has been killed yet. It is told in verse 6: 19 that the greatest Witness is Allah and Adhikr—Allah’s Message. The believer, by utilizing Adhikr as a Shield and Safeguard against all types of disasters, diseases, and Hellfire, will make Adhikr a Witness and Proof in favor of them. See explanation 10: 103; 11: 17-20, 103; 30: 47; 39: 69.
