It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever builds a mosque (for the pleasure of Allah), Allah, Glorified and Exalted, will prepare for him a magnificent house in Paradise in return." The Mother of the Believers (may Allah be pleased with her) said: I asked: "O Messenger of Allah (peace and blessings be upon him)! Even these mosques (deserve the same reward) that are built along the road to Makkah?" He (peace and blessings be upon him) said: "Yes, those too (are included in this virtue)."
Imam Ibn Abi Umar narrated this same narration through Marwan from Kathir al-Mu'addib, in which these words are added: "Even if it (the mosque) is the size of the nest (the egg-laying spot) of a qata bird."
