It is narrated from Sayyiduna Fadalah bin Ubayd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Islam is a spacious house; whoever enters it, it accommodates him. And Hijrah is a spacious house; whoever enters it, it accommodates him. Whoever is invited to Islam and accepts Islam, and is invited to Hijrah and emigrates, has left no good unsought and no escape from evil untaken."
