عَنْ مُعَاذِ بْنِ جَبَلِ رَضِيَ اللَّهُ عَنْهُ قَالَ: جَاءَ رَجُلٌ مِنَ الْأَنْصَارِ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ: إِنِّي رَأَيْتُ فِي النَّوْمِ كَأَنِّي مُسْتَيْقِظٌ أَرَى رَجُلًا نَزَلَ مِنَ السَّمَاءِ عَلَيْهِ بُرْدَانٌ أَخْضَرَانِ نَزَلَ عَلَى جِذْمِ حَائِطٍ مِنَ الْمَدِينَةِ فَأَذَّنَ مَثْنَى مَثْنَى ثُمَّ جَلَسَ، ثُمَّ أَقَامَ فَقَالَ مَثْنَى مَثْنَى، قَالَ: ((نِعْمَ مَا رَأَيْتَ، عَلِّمْهَا بِلَالًا)) قَالَ عُمَرُ: قَدْ رَأَيْتُ مِثْلَ ذَلِكَ وَلَكِنَّهُ سَبَقَنِي
Sayyiduna Mu’adh bin Jabal (may Allah be pleased with him) says: An Ansari man came to the Messenger of Allah (peace and blessings be upon him) and said: I saw a dream, it seemed to me as if I was awake, a man descended from the sky to one side of a garden in Madinah, wearing two green sheets over himself. He called the adhan with two-word phrases, then sat down, then he called the iqamah with two-word phrases. The Prophet (peace and blessings be upon him) said: You have seen the best thing; teach these words to Bilal. Sayyiduna ‘Umar bin Khattab (may Allah be pleased with him) said: Indeed, I also saw such a dream, but he has preceded me.
