It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him), he states that the Messenger of Allah (peace and blessings be upon him) said: "Count all those who have accepted Islam." We said: O Messenger of Allah! Are you afraid for us, even though our number is between six hundred and seven hundred? The Messenger of Allah (peace and blessings be upon him) said: "You do not know (the reality of the situation), perhaps you will fall into trials." The narrator says: Then we were tested to such an extent that one of us had to pray secretly (that is, due to certain reasons, he could not pray openly).
