`Abdullah bin Imam Ahmad recorded from Mu`adh bin `Abdullah bin Khubayb, who
reported that his father said, "We became thirsty and it had become dark while
we were waiting for the Messenger of Allah to lead us in prayer. Then, when he
came out he took me by my hand and said,
«قُل»
(Say.) Then he was silent. Then he said again,
«قُل»
(Say.) So I said, `What should I say' He said,
[قُلْ هُوَ اللَّهُ
أَحَدٌ ]
وَالْمُعَوِّذَتَيْنِ
حِينَ تُمْسِي وَحِينَ تُصْبِحُ ثَلَاثًا، تَكْفِكَ كُلَّ يَوْمٍ
مَرَّتَيْن»
(Say: "He is Allah, One,'' and the two Surahs of Refuge (Al-Falaq and An-Nas)
when you enter upon the evening and the morning three times (each). They will be
sufficient for you two times every day.)'' This Hadith was also recorded by Abu
Dawud, At-Tirmidhi and An-Nasa'i. At-Tirmidhi said, "Hasan Sahih Gharib.''
An-Nasa'i also recorded through another chain of narrators with the wording,
«يَكْفِكَ كُلَّ
شَيْء»
(They will suffice you against everything.)
