It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Seek help from the pre-dawn meal (suhur) for the day's fast, and seek help from the midday rest (qaylulah) for standing in prayer at night." Zam'ah bin Salih and Salamah bin Wahram are not abandoned narrators who cannot be used as evidence, but the two Shaykhs did not narrate from them; and this is among the finest hadiths on this topic.
