[Machine] I entered the mosque and saw the Messenger of Allah ﷺ coming out of the mosque, so I followed him and walked behind him without him realizing I was there until he entered a date palm grove and faced the qibla (direction of prayer) and prostrated. He prolonged the prostration, and I was behind him until I thought that Allah Almighty had taken his soul, so I approached to see, and I lowered my head to take a look at his face. He raised his head and said, "What is it, O Abdullah Ibn Mas'ud?" So I said, "When you prolonged the prostration, O Messenger of Allah, I was afraid that Allah had taken your soul, so I approached to see." He said, "When you saw me, I entered the date palm grove and met Jibril (Gabriel), ﷺ , who said to me, 'I give you glad tidings that Allah Almighty says: Whoever sends peace upon you, I send peace upon him, and whoever sends blessings upon you, I send blessings upon him.'"
دَخَلْتُ الْمَسْجِدَ فَرَأَيْتُ رَسُولَ اللهِ ﷺ خَارِجًا مِنَ الْمَسْجِدِ فَاتَّبَعْتُهُ أَمْشِي وَرَاءَهُ وَلَا يَشْعُرُ بِي حَتَّى دَخَلَ نَخْلًا فَاسْتَقْبَلَ الْقِبْلَةَ فَسَجَدَ فَأَطَالَ السُّجُودَ وَأَنَا وَرَاءَهُ حَتَّى ظَنَنْتُ أَنَّ اللهَ تَعَالَى تَوَفَّاهُ فَأَقْبَلْتُ أَمْشِي حَتَّى جِئْتُهُ فَطَأْطَأْتُ رَأْسِي أَنْظُرُ فِي وَجْهِهِ فَرَفَعَ رَأْسَهُ فَقَالَ مَا لَكَ يَا عَبْدَ الرَّحْمَنِ؟ فَقُلْتُ لَمَّا أَطَلْتَ السُّجُودَ يَا رَسُولَ اللهِ خَشِيتُ أَنْ يَكُونَ اللهُ قَدْ تَوَفَّى نَفْسَكَ فَجِئْتُ أَنْظُرُ فَقَالَ إِنِّي لَمَّا رَأَيْتَنِي دَخَلْتُ النَّخْلَ لَقِيتُ جَبْرَائِيلَ عَلَيْهِ السَّلَامُ فَقَالَ أُبَشِّرُكَ أَنَّ اللهَ تَعَالَى يَقُولُ مَنْ سَلَّمَ عَلَيْكَ سَلَّمْتُ عَلَيْهِ وَمَنْ صَلَّى عَلَيْكَ صَلَّيْتُ عَلَيْهِ
