From amongst the Angels is the Angel charged with the human sperm and its transformation until its creation is completed. From amongst them are those charged with safeguarding of the Children of Aadam (may the Salutations of Allaah be upon Him), as Allaah has said:
﴿لَهُۥ مُعَقِّبَٰتٞ مِّنۢ بَيۡنِ يَدَيۡهِ وَمِنۡ خَلۡفِهِۦ يَحۡفَظُونَهُۥ مِنۡ أَمۡرِ ٱللَّهِۗ ١١﴾ [ الرّعد: ۱۱]

﴿وَهُوَ ٱلۡقَاهِرُ فَوۡقَ عِبَادِهِۦۖ وَيُرۡسِلُ عَلَيۡكُمۡ حَفَظَةً حَتَّىٰٓ إِذَا جَآءَ أَحَدَكُمُ ٱلۡمَوۡتُ تَوَفَّتۡهُ رُسُلُنَا وَهُمۡ لَا يُفَرِّطُونَ ٦١﴾ [ الأنعام:٦۱]
“And He is the subjugator over His servants, and He sends over you guardian-angels until, when death comes to one of you, our messengers take him, and they do not fail [in their duties]”. [Al An'am:61]

((اللهُمَّ رَبَّ جِبْرَائِيلَ، ومِيكَائِيلَ، وإِسْرَافِيلَ، فَاطِرَ السَمَاوَاتِ والأَرْضِ، عَالِمَ الغَيْبِ وَالشَّهَادَةِ، أَنْتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِيمَا كَانُو فِيهِ يَخْتَلِفُونَ، اهْدِنِي لمِاَ اخْتُلِفَ فِيهِ مِنَ الحَقِ بِإِذْنِكَ، إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُسْتَقِمٍ))
“Oh Allaah, the Lord of Jibreel, Meekaeel and Israafeel, the Originator of the Heavens and the Earth, the Knower of the unseen and the seen, You Judge between your slaves in whatever they differ in, guide me by your might in whatever they differ in from the truth, verily, You guide whoever you wish to the correct path”
Reported by al-Imaam Muslim (may Allaah be merciful upon Him) in the Book of the Prayer of the Traveler and its Reduction, hadeeth No. 770.
