The first seven people to openly declare their Islam were the Messenger of Allah ﷺ, Abu Bakr, Ammar, his mother Sumayy, Suhayb, Bilal, and Miqdad.As for the Messenger of Allah ﷺ, Allah protected him through his uncle Abu Talib. As for Abu Bakr, Allah protected him through his clan. As for the rest, the polytheists seized them, clothed them in iron armor, and left them to roast in the sun. Every one of them eventually gave in to what their captors wanted, except Bilal. He held his own life cheap for the sake of Allah, and his people held him cheap as well. They seized him and handed him over to the children, who began to drag him through the streets of Mecca while he kept saying, "One, One."
حدثنا أحمد بن سعيد الدارمي حدثنا يحيى بن أبي بكير حدثنا زائدة بن قدامة عن عاصم بن أبي النجود عن زر بن حبيش
كان أول من أظهر إسلامه سبعة رسول الله ﷺ وأبو بكر وعمار وأمه سمية وصهيب وبلال والمقداد فأما رسول الله ﷺ فمنعه الله بعمه أبي طالب وأما أبو بكر فمنعه الله بقومه وأما سائرهم فأخذهم المشركون وألبسوهم أدراع الحديد وصهروهم في الشمس فما منهم من أحد إلا وقد واتاهم على ما أرادوا إلا بلالا فإنه هانت عليه نفسه في الله وهان على قومه فأخذوه فأعطوه الولدان فجعلوا يطوفون به في شعاب مكة وهو يقول أحد أحد
