Ten good deeds

Imran ibn Hussein reported: A man came to the Prophet, peace be upon him, and he said, “Peace be upon you.” The Prophet said, “Ten good deeds.” Then another man came to the Prophet and he said, “Peace be upon you and the mercy of Allah.” The Prophet said, “Twenty good deeds.” Then another man came to the Prophet and he said, “Peace be upon you and the mercy of Allah and His blessings.” The Prophet said, “Thirty good deeds.”

عَنْ عِمْرَانَ بْنِ حُصَيْنٍ أَنَّ رَجُلًا جَاءَ إِلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ السَّلَامُ عَلَيْكُمْ قَالَ قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَشْرٌ ثُمَّ جَاءَ آخَرُ فَقَالَ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللَّهِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِشْرُونَ ثُمَّ جَاءَ آخَرُ فَقَالَ السَّلَامُ عَلَيْكُمْ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ثَلَاثُونَ

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ
