May Allah be pleased with him said

“The Messenger of Allah (ﷺ) used to order that when one of us went to sleep, he should say: ‘O Allah, Lord of the heavens and Lord of the earths, and our Lord, and the Lord of everything, splitter of the seed-grain and date-stone, and Revealer of the Tawrah and the Injil and the Qur’an. I seek refuge in You from the evil of every evil that You are holding by the forelock. You are the First, there is nothing before You, You are the Last, there is nothing after You, and Az-Zahir, there is nothing above you, and Al-Batin, there is nothing below You. Relieve me of my debt, and enrich me from poverty (Allāhumma rabbas-samāwati wa rabbal-arḍīna wa rabbanā, wa rabba kulli shai’in, fāliqal-ḥabbi wan-nawā, wa munzilat-Tawrāti wal-Injīli wal-Qur’ān. A`ūdhu bika sharri kulli dhi sharrin anta ākhidhun bināṣiyatihi, antal-Awwalu falaisa qablaka shai’un, wa antal-Ākhiru falaisa ba`daka shai’un, waẓ-Ẓāhiru falaisa fauqaka shai'un wal-Bātinu falaisa dūnaka shai’un, iqḍi `annid-daina wa aghninī minal-faqr).’”
