(Whoso disbelieveth in Allah after his belief…) [16:106]. Said Ibn 'Abbas: “This verse was revealed about 'Ammar ibn Yasir. The idolaters had taken him away along with his father Yasir, his mother Sumayyah, Suhayb [al-Rumi], Bilal [ibn Rabah], Khabbab [ibn al-Aratt] and Salim [the client of Hudhayfah] and tortured them. As for Sumayyah, she was tied up between two camels and stabbed with a spear in her female organ. She was told: 'You embraced Islam for the men', and was then killed. Her husband Yasir was also killed. They were the first two persons who were killed in Islam. As for 'Ammar, he was coerced to let them hear what they wanted to hear. The Messenger of Allah, Allah bless him and give him peace, was told that 'Ammar has renounced faith, but he said: 'Never, 'Ammar is filled with faith from his head to his toes; faith is admixed with his flesh and blood!' 'Ammar then went to see the Messenger of Allah, Allah bless him and give him peace, crying. The Messenger of Allah, Allah bless him and give him peace, wiped his tears with his own hand and said: 'if they return to you, let them hear again what you told them'. Then, Allah, exalted is He, revealed this verse”. Mujahid said: “This verse was revealed about some Meccans who accepted faith. The Muslims of Medina wrote to them urging them to migrate and told them that they did not consider them part of them unless they migrated. And so they left Mecca intending to migrate to Medina. The Quraysh caught up with them on the way and coerced them to renounce their faith. It is about them that this verse was revealed”.
