The monk asked, “Has Ahmed (sallallahu ‘alaihi wasallam) appeared yet?” I asked the monk for further clarification saying, “Who?” The monk replied, “The son of ‘Abdullah bin ‘Abdil Muttalib. This is the month in which he will appear. He will appear in the Haram of Makah Mukarramah and migrate to a rocky land (a mountainous area) that has abundant date palms. He is the last of the Ambiyaa (‘alaihimus salaam) and the final Nabi. Do not delay in following him.”

The conversation with the monk had a profound effect on my heart. I immediately returned to Makkah Mukarramah and asked the people whether anything new had transpired in my absence. They replied, “Yes, Muhammed (sallallahu ‘alaihi wasallam), the trustworthy, has claimed prophethood, and the son of Abu Quhaafah (Hazrat Abu Bakr (radhiyallahu ‘anhu)) has joined him.”

Without delay, I went to Hazrat Abu Bakr (radhiyallahu ‘anhu) who took me to Rasulullah (sallallahu ‘alaihi wasallam). On arriving in the blessed presence of Rasulullah (sallallahu ‘alaihi wasallam), I embraced Islam and also gave him a detailed account of what had transpired between the monk and myself at Busraa.
