ISRAFIL OR ISRAFEEL
Israfil is an angel mentioned in the Islamic scriptures. He is the blower of the Trumpet on Qiyamah.
The angels are not partners, associates, or rivals with Allah, nor are they His children; but one must still respect and love them. Allah says: "And they say: ‘The Most Beneficent (Allah) has begotten a child [from the angels].’ Far removed is He from every imperfection! They (the angels) are but honored slaves. They speak not until He has spoken, and [then] they act on His Command." (Quran Surah 21:26-27)
They spend their time worshipping and obeying Allah, glorifying Him and praising Him. Allah says: "They (i.e. the angels) glorify His praises night and day, (and) without slackening (to do so)." (Quran Surah 21:20)
Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:Messenger of Allah (ﷺ) said, "How can I feel at ease when the Angel of the Trumpet, (Israfil) has put his lips to the Trumpet and is waiting for the order to blow it". He (ﷺ) perceived as if this had shocked his Companions, so he (ﷺ) told them to seek comfort through reciting: 'Hasbunallah wa ni'mal-Wakil [Allah (Alone) is Sufficient for us, and He is the Best Disposer of affairs (for us)]". Tirmidhi Vol. 4, Book 11, Hadith 2431
'Abd al-Rahman b. 'Auf reported: I asked 'A'isha, the mother of the believers, (to tell me) the words with which the Messenger of Allah (ﷺ) commenced the prayer when he got up at night. She said: When he got up at night he would commence his prayer with these words: O Allah, Lord of Gabriel, and Michael, and Israfil, the Creator of the heavens and the earth, Who knowest the unseen and the seen; Thou decidest amongst Thy servants concerning their differences. Guide me with Thy permission in the divergent views (which the people) hold about Truth, for it is Thou Who guidest whom you will to the Straight Path.
اللَّهُمَّ رَبَّ جِبْرَائِيلَ وَمِيكَائِيلَ وَإِسْرَافِيلَ فَاطِرَ السَّمَوَاتِ وَالأَرْضِ عَالِمَ الْغَيْبِ وَالشَّهَادَةِ أَنْتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ اهْدِنِي لِمَا اخْتُلِفَ فِيهِ مِنَ الْحَقِّ بِإِذْنِكَ إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُسْتَقِيمٍSahih Muslim 770
