[Machine] Salman may Allah be pleased with him, said, "O Abu Abdullah, Omar asked me about an incident. I said: I entered upon the Messenger of Allah ﷺ while he was leaning on a pillow, so he threw it to me and said, 'O Salman, whenever a Muslim enters upon his Muslim brother and throws a pillow to him in honor of him, Allah will forgive him.'"

سَلْمَانُ صَدَقَ اللَّهُ وَرَسُولُهُ فَقَالَ عُمَرُ حَدِّثْنَا يَا أَبَا عَبْدِ اللَّهِ قَالَ دَخَلْتُ عَلَى رَسُولِ اللَّهِ ﷺ وَهُوَ مُتَّكِئٌ عَلَى وِسَادَةٍ فَأَلْقَاهَا إِلَيَّ ثُمَّ قَالَ لِي «يَا سَلْمَانُ مَا مِنْ مُسْلِمٍ يَدْخُلُ عَلَى أَخِيهِ الْمُسْلِمِ فَيُلْقِي لَهُ وِسَادَةً إِكْرَامًا لَهُ إِلَّا غَفَرَ اللَّهُ لَهُ»

[Machine] Salman entered upon Umar while he was reclining on a cushion. Salman threw it to him and said, "Allahu Akbar! Allah and His Messenger spoke truthfully." Umar then said, "Tell us, O Abu Abdullah." Salman said, "I entered upon the Messenger of Allah ﷺ while he was reclining on a cushion, and he threw it to me. Then he said, 'O Salman, there is no Muslim who enters upon his Muslim brother and throws a cushion to him as a gesture of respect, except that Allah will forgive him.'"
