Ubayy reported, "I used to spend the night near the door of the Prophet ﷺ and would bring him his water for ablution. I would hear him for long stretches of the night saying, 'Allah hears whoever praises Him,' and I would hear him for long stretches of the night reciting, 'Praise be to Allah, Lord of the worlds' [Fatihah 1:2]."
كنت أبيت عند باب النبي ﷺ فأعطيه وضوءه فأسمعه الهوي من الليل يقول: سمع الله لمن حمده وأسمعه الهوي من الليل يقول: {الحمد لله رب العالمين}
Tirmidhi (3416) narrated it from Ishaq bin Mansur, who said, Nadr bin Shumayl, Wahb bin Jareer, Abu Amir Aqadi, and Abdul-Samad bin Abdul-Warith told us, they said, Hisham Dastawai told us, from Yahya bin Abu Kathir, from Abu Salama, Rabia bin Kaab told me, and he related it. Tirmidhi said, hasan sahih.Imam Ahmad (16576, 16575) also narrated it through other routes, from Hisham, in the same manner. Nasai (1618) and Ahmad (16574) both narrated it through the route of Mamar, and Ahmad paired him with Uzai, both from Yahya bin Abu Kathir, and in it he says, referring to ﷺ, "Glory be to Allah, Lord of the worlds," for a period of time, then he says, "Glory be to Allah and praise be to Him," for a period of time.Ibn Majah (3879) narrated it from the hadith of Shayban, from Yahya, in the same manner. However, Abu Awana (2235) narrated it through the route of Walid bin Muslim, who said, Uzai told us, from Yahya, and in it, "Glory be to my Lord and praise be to Him, glory be to my Lord and praise be to Him, glory be to my Lord and praise be to Him, glory be to the Lord of the worlds," three times, for a period of time. Walid bin Muslim is a mudallis, but here he stated his source explicitly.The origin of this hadith of Rabia is in Sahih Muslim (489), through the route of Hiqal bin Ziyad, who said, I heard Uzai say, Yahya bin Abu Kathir told me, he said, Abu Salama told me, he said, Rabia bin Kaab Aslami told me, he said, I used to spend the night with the Messenger of Allah ﷺ, so I would bring him his water for wudu and his needs, and he said to me, "Ask." I said, "I ask you for your companionship in Paradise." He said, "Or something else?" I said, "That is it." He said, "Then help me for yourself by frequent sujud." Its citation was given previously in the chapter on the merit of sujud and the encouragement toward it.It appears that Rabia used to narrate all of this together, but some of the narrators divided it into parts. Al-hawiyy means a period of time during the night. It contains an indication that the Prophet ﷺ used to prolong his night prayer standing.This Rabia was one of the People of the Suffa, and he remained with the Prophet ﷺ until he passed away. He then left Madinah and settled in the lands of the Aslam tribe, a day's journey from Madinah, and he lived through the days of the Harra, and died at the Harra in the year sixty-three, in Dhul-Hijjah.
