It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When any of you comes to his bed, let him say: 'Allahumma Rabba al-samawati wa Rabba al-ard, Rabbana wa Rabba kulli shay'in, anta akhidhun bi-nasiyatihi, anta al-awwalu fa-laysa qablaka shay'un, wa anta al-akhiru fa-laysa ba'daka shay'un, wa anta al-batinu fa-laysa dunaka shay'un, aghnina min al-faqri waqdi 'anna al-dayn' (O Allah, Lord of the heavens and Lord of the earth, our Lord and the Lord of everything, You are the One who holds everything by its forelock; You are the First, so there is nothing before You; You are the Last, so there is nothing after You; You are the Hidden, so there is none besides You (who knows the secrets); free us from poverty and settle our debt for us)." The chain of this hadith is sahih (authentic), but the two Shaykhs (Bukhari and Muslim) did not record it, and the narrator Yusuf in this report is the one who is called Mawla Sukkarah.
