حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه – ‏<a href="https://quran.com/53/18-18">{‏لَقَدْ رَأَى مِنْ آيَاتِ رَبِّهِ الْكُبْرَى‏}</a>‏ قَالَ رَأَى رَفْرَفًا أَخْضَرَ سَدَّ أُفُقَ السَّمَاءِ‏.‏

بَابُ إِذَا قَالَ أَحَدُكُمْ آمِينَ. وَالْمَلاَئِكَةُ فِي السَّمَاءِ، فَوَافَقَتْ إِحْدَاهُمَا الأُخْرَى، غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ

Narrated `Abdullah:

Regarding the Verse: "Indeed he (Muhammad) did see. Of the Signs of his Lord, The Greatest!" 
(53.18) That the Prophet (ﷺ) had seen a green carpet spread all over the horizon of the sky.

If anyone says Amin [during the Salat (prayer) at the end of the recitation of Surat Al-Fatiha]

Sahih al-Bukhari

حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه – ‏<a href="https://quran.com/53/18-18">{‏لَقَدْ رَأَى مِنْ آيَاتِ رَبِّهِ الْكُبْرَى‏}</a>‏ قَالَ رَأَى رَفْرَفًا أَخْضَرَ قَدْ سَدَّ الأُفُقَ‏.‏

باب ‏<a href="https://quran.com/53/18-18">{‏لَقَدْ رَأَى مِنْ آيَاتِ رَبِّهِ الْكُبْرَى‏}</a>‏

Narrated `Abdullah:

(regarding the revelation) Truly he (Muhammad) did see of the signs of his Lord; the Greatest!' 
(53.18) The Prophet (ﷺ) saw a green screen covering the horizon.

"Indeed he (Muḥammad pbuh) did see of the Greatest Signs of his Lord (Allah)." (V.53:18)

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِيُّ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ الشَّيْبَانِيِّ، سَمِعَ زِرَّ بْنَ حُبَيْشٍ، عَنْ عَبْدِ اللَّهِ، قَالَ ‏<a href="https://quran.com/53/18-18">{‏ لَقَدْ رَأَى مِنْ آيَاتِ رَبِّهِ الْكُبْرَى‏}</a>‏ قَالَ رَأَى جِبْرِيلَ فِي صُورَتِهِ لَهُ سِتُّمِائَةِ جَنَاحٍ ‏.‏

باب فِي ذِكْرِ سِدْرَةِ الْمُنْتَهَى ‏‏

Zirr b. Hubaish narrated it on the authority of 'Abdullah (that the words of Allah):" Certainly he saw of the greatest signs of Allah" (al-Qur'an, liii. 18) imply that he saw Gabriel in his (original) form and he had six hundred wings.
