Abu Sa'id Al-Khudri (May Allah be pleased with him) reported:
The 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)]".
[At-Tirmidhi]
