عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ قَالَ: ”كَيْفَ أَنْعَمُ وَقَدِ الْتَقَمَ صَاحِبُ الْقَرْنِ الْقَرْنَ وَحَنَى جَبْهَتَهُ وَأَصْغَى سَمْعَهُ يَنْتَظِرُ مَتَى يُؤْمَرُ“، قَالَ الْمُسْلِمُونَ: يَا رَسُولَ اللَّهِ! فَمَا نَقُولُ؟ قَالَ: ”قُولُوا حَسْبُنَا اللَّهُ وَنِعْمَ الْوَكِيلُ، عَلَى اللَّهِ تَوَكَّلْنَا“
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: How can I rejoice when the angel entrusted with the trumpet has placed the trumpet to his mouth, lowered his forehead, and is attentively listening for the command from Allah Almighty as to when he will be ordered to blow the trumpet? Upon hearing this, the Muslims asked: O Messenger of Allah! What should we say? The Prophet (peace and blessings be upon him) said: You should say: Ḥasbunallāhu wa ni‘mal-wakīl, ‘alallāhi tawakkalnā — Allah is sufficient for us, and He is the best disposer of affairs; upon Allah alone we have placed our trust.
