It is narrated from the Mother of the Believers Sayyidah Aishah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) said: "Whoever recites the Qur'an, in whatever manner (of recitation) it may be, Allah Almighty writes for him ten good deeds, erases ten of his sins and raises him ten degrees. Whoever recites, pronouncing some parts with correct grammatical endings and making mistakes in some, twenty good deeds are written for him, twenty sins are erased from him and he is raised twenty degrees. And whoever recites the Qur'an and renders all of it with correct grammatical endings (proper rules), forty good deeds are written for him, forty of his sins are erased and he is raised forty degrees."
Only Zayd al-Ammi (may Allah have mercy on him) narrated this hadith from Urwah, and Abd al-Rahim bin Zayd (may Allah have mercy on him) is alone in narrating it.
