In his Musnad, Al-Hafiz Abu Ya`la Ahmad bin `Ali bin Al-Muthanna Al-Mawsili reported that Ubayy bin Ka`b said, "Two men disputed with each other in the presence of the Messenger of Allah and the nose of one of them became swollen because of extreme anger. The Messenger of Allah said,
« إِنِّي لَأَعْلَمُ شَيْئًا لَوْ قَالَهُ لَذَهَبَ عَنْهُ مَا يَجِدُ: أَعُوذُ بِاللهِ مِنَ الشَّيْطَانِ الرَّجِيمِ »
(I know of some words that if he said them, what he feels will go away, 'I Seek Refuge with Allah from the cursed Satan.')''
An-Nasa'i also recorded this Hadith in his book, Al-Yawm wal-Laylah.
Al-Bukhari recorded that Sulayman bin Surad said, "Two men disputed in the presence of the Prophet while we were sitting with him. One of them was cursing the other fellow and his face turned red due to anger. The Prophet said,
« إِنِّي لَأَعْلَمُ كَلِمَةً لَوْ قَالَهَا لَذَهَبَ عَنْهُ مَا يَجِدُ، لَوْ قَالَ: أَعُوذُ بِاللهِ مِنَ الشَّيْطَانِ الرَّجِيمِ »
(I know of a statement which if he said it, will make what he feels disappear, `I seek refuge with Allah from the cursed Satan.') They said to the man, `Do you not hear what the Messenger of Allah is saying' He said, `I am not insane.'' Also, Muslim, Abu Dawud and An-Nasa'i recorded this Hadith.
There are many other Hadiths about seeking refuge with Allah. One can find this subject in the books on supplication and the virtues of righteous, good deeds.The majority of the scholars state that reciting the Isti`adhah (in the prayer and when reciting the Qur'an) is recommended and not required, and therefore, not reciting it does not constitute a sin. However, Ar-Razi recorded that `Ata' bin Abi Rabah said that the Isti`adhah is required in the prayer and when one reads the Qur'an. In support of `Ata's statement, Ar-Razi relied upon the apparent meaning of the Ayah,
﴿ فَٱسۡتَعِذۡ ﴾
The Isti`adhah cleanses the mouth from the foul speech that it has indulged in. It also purifies the mouth and prepares it to recite the speech of Allah. Further, the Isti`adhah entails seeking Allah's help and acknowledging His ability to do everything. The Isti`adhah also affirms the servant's meekness, weakness and inability to face the enemy of his inner evil, whom Allah alone, Who created this enemy, is able to repel and defeat. This enemy does not accept kindness, unlike the human enemy. There are three Ayat in the Qur'an that affirm this fact. Also, Allah said,
﴿ إِنَّ عِبَادِى لَيۡسَ لَكَ عَلَيۡهِمۡ سُلۡطَـٰنٌ۬ۚ وَكَفَىٰ بِرَبِّكَ وَڪِيلاً۬ ﴾
(Verily, My servants (i.e. the true believers of Islamic Monotheism) ـ you have no authority over them. And sufficient is your Lord as a Guardian.) (17:65).
We should state here that the believers, whom the human enemies kill, become martyrs, while those who fall victim to the inner enemy - Satan - become bandits. Further, the believers who are defeated by the apparent enemy - disbelievers - gain a reward, while those defeated by the inner enemy earn a sin and become misguided. Since Satan sees man where man cannot see him, it is befitting that the believers seek refuge from Satan with Whom Satan cannot see. The Isti`adhah is a form of drawing closer to Allah and seeking refuge with Him from the evil of every evil creature.
