It is narrated from Sayyiduna Suhail bin Bayda’ (may Allah be pleased with him), he says: We were on a journey with the Messenger of Allah (peace and blessings be upon him), while I was riding behind him on his mount. The Messenger of Allah (peace and blessings be upon him) called out loudly two or three times:“O Suhail bin Bayda’!”Sayyiduna Suhail (may Allah be pleased with him) would respond from ahead. Anyway, when the Companions heard the Messenger of Allah (peace and blessings be upon him) calling out in this manner, they thought that he wanted to call all of them, so those in front stopped and those behind caught up with the Messenger of Allah (peace and blessings be upon him), until they all gathered together. Then the Messenger of Allah (peace and blessings be upon him) said:“Whoever bears witness that Allah alone is the true deity, Allah makes the Fire forbidden for him and makes Paradise obligatory for him.”In another narration:“Because of this testimony, Allah makes Paradise obligatory for him and frees him from the Fire.”
