Sunan Abi Dawud, Hadith 558 ⓘ

Narrated AbuUmamah: The Messenger of Allah said: If anyone goes out from his house after performing ablution for saying the prescribed prayer in congregation (in the mosque), his reward will be like that of one who goes for hajj pilgrimage after wearing ihram (robe worn by the hajj pilgrims). And he who goes out to say the mid-morning (duha) prayer, and takes the trouble for this purpose, will take the reward like that of a person who performs umrah. And a prayer followed by a prayer with no worldly talk during the gap between them will be recorded in Illiyyun.

حَدَّثَنَا أَبُو تَوْبَةَ، حَدَّثَنَا الْهَيْثَمُ بْنُ حُمَيْدٍ، عَنْ يَحْيَى بْنِ الْحَارِثِ، عَنِ الْقَاسِمِ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ أَبِي أُمَامَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ خَرَجَ مِنْ بَيْتِهِ مُتَطَهِّرًا إِلَى صَلاَةٍ مَكْتُوبَةٍ فَأَجْرُهُ كَأَجْرِ الْحَاجِّ الْمُحْرِمِ وَمَنْ خَرَجَ إِلَى تَسْبِيحِ الضُّحَى لاَ يُنْصِبُهُ إِلاَّ إِيَّاهُ فَأَجْرُهُ كَأَجْرِ الْمُعْتَمِرِ وَصَلاَةٌ عَلَى أَثَرِ صَلاَةٍ لاَ لَغْوَ بَيْنَهُمَا كِتَابٌ فِي عِلِّيِّينَ ‏" ‏ ‏.‏
