SALAATUL-QATL

When a Muslim is about to be killed, it is mustahab for him to offer two rakaats of salaat and make dua to Allah Ta'ala and ask Him to forgive him his sins. This is so that this salaat and dua of his will be his last act in this world.

Hadith : Once Rasulullah sallallahu alayhi wa sallam had sent a few qaaris from among his companions to a certain place in order to teach the Quran. During the course of the journey, the kuffaar of Makkah captured them. Apart from Hadrat Khubayb radiallahu anhu, they killed all the other companions at that very spot. They took Hadrat Khubayb radiallahu anhu to Makkah in a great procession and they martyred him with great pomp and ceremony. When he was about to be martyred, he asked them for permission and offered two rakaats of salaat. Since then, this salaat became mustahab .
