[Machine] The Prophet ﷺ said, "Whoever sends blessings upon me sincerely from their heart, Allah will send blessings upon them tenfold, raise them by ten levels, write for them ten rewards, and erase from them ten sins." Abu Usamah Hammad ibn Usamah contradicted him and narrated from Sa'id ibn Sa'id from Sa'id ibn 'Umayr from his uncle 9810, Zakariyya ibn Yahya informed me that Abu Kurayb narrated to us that Abu Usamah narrated to us from Sa'id ibn Sa'id from Sa'id ibn 'Umayr ibn 'Uqbah ibn Ni'yar from his uncle Abu Burdah ibn Ni'yar that the Messenger of Allah ﷺ said this and something similar.  

الكبرى للنسائي:٩٨٠٩أَخْبَرَنَا الْحُسَيْنُ بْنُ حُرَيْثٍ قَالَ حَدَّثَنَا وَكِيعٌ عَنْ سَعِيدٍ وَهُوَ ابْنُ سَعِيدٍ عَنْ سَعِيدِ بْنِ عُمَيْرٍ الْأَنْصَارِيِّ عَنْ أَبِيهِ وَكَانَ بَدْرِيًّا قَالَ

قَالَ رَسُولُ اللهِ ﷺ «مَنْ صَلَّى عَلَيَّ مِنْ أُمَّتِي صَلَاةً مُخْلِصًا مِنْ قَلْبِهِ صَلَّى الله عَلَيْهِ بِهَا عَشْرَ صَلَوَاتٍ وَرَفَعَهُ بِهَا عَشْرَ دَرَجَاتٍ وَكَتَبَ لَهُ بِهَا عَشْرَ حَسَنَاتٍ وَمَحَا عَنْهُ عَشْرَ سَيِّئَاتٍ» خَالَفَهُ أَبُو أُسَامَةَ حَمَّادُ بْنُ أُسَامَةَ رَوَاهُ عَنْ سَعِيدِ بْنِ سَعِيدٍ عَنْ سَعِيدِ بْنِ عُمَيْرٍ عَنْ عَمِّهِ 9810 أَخْبَرَنِي زَكَرِيَّا بْنُ يَحْيَى قَالَ حَدَّثَنَا أَبُو كُرَيْبٍ قَالَ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ سَعِيدِ بْنِ سَعِيدٍ عَنْ سَعِيدِ بْنِ عُمَيْرِ بْنِ عُقْبَةَ بْنِ نِيَارٍ عَنْ عَمِّهِ أَبِي بُرْدَةَ بْنِ نِيَارٍ قَالَ قَالَ رَسُولُ اللهِ ﷺ فَذَكَرَ نَحْوَهُ
