Aisha reported: When the Messenger of Allah, peace and blessings be upon him, would lie down for sleep, he would blow into his hands, recite the two chapters of refuge, Surat al-Falaq and al-Nas, and he would wipe his hands over his body. (Bukhari)
“It is reported in the Sunan of Abu Dawud and Ibn Maajah from Asmaa’ bint ‘Umays (radhiya Allahu ‘anhaa) that she said, ‘Rasulullah (‘Sallallahu ‘alayhi wa ‘alaa aalihi wa sallam) said to me,
“Shall I teach you some words that you should say at the time of كرب Karb or in Karb (heartache, distress, gloom)? Say:
أَللَّهُ أَللَّهُ رَبِّي لَا أُشْرِكُ بِهِ شَيْئًا “Allahu Allahu Rabbi Laa Ushriku Bihi Shai’a”
Abu Hurairah (may Allah be pleased with him) reported that whenever the Prophet, peace and blessings of Allah be upon him, was faced with a serious difficulty, he would raise his head to the sky and supplicate, “Subhan-Allah al-’Azim (glory be to Allah, the Mighty).” And when he implored seriously and strongly, he would say, “Ya Hayyu, Ya Qayyum (O the Living, the Eternal One).” (Tirmidhi)
