Sayyiduna Abu Umamah (may Allah be pleased with him) said concerning the saying of Allah Almighty: "And in part of the night, offer the night prayer (tahajjud) with it as an additional (nafilah) prayer for you": "This additional (obligation) was only for the Prophet (peace and blessings be upon him)."
No one narrated this hadith from al-Hasan bin Abi al-Hasna' (may Allah have mercy on him) except Abu Qutaybah (may Allah have mercy on him) and Ali bin Nasr al-Jahdami (may Allah have mercy on him).
