Who is the Companion whom the Messenger of Allah, peace and blessings be upon him, took his house as a secret center for the Da'wah: is he Mus'ab ibn 'Umair or Al-Arqam? And what is the name of Sayyiduna Noah's son: is he Sam, Amjad, or Akram?

The Prophet, may Allah’s prayers and peace be upon him, took the house of Al-Arqam ibn Abi al-Arqam al-Makhzumi in Mecca as a secret place for his companions to gather and be taught. This was because he was not known to be a Muslim, and he belonged to Banu Makhzum, who were enemies of Banu Hashim. Additionally, his young age (16 years old) diverted attention away from his house as a meeting place. As for the sons of our master Noah, peace be upon him, they were: Sam, Ham, and Japheth (who were Muslims and survived), and Yam (who was a disbeliever and drowned). He is the one mentioned in the Almighty’s saying: {And Noah called to his son, and he was in an isolated place, “O my son, embark with us and do not be with the disbelievers”} [Hud:42].
