Mishkat al-Masabih 4 Prayer كتاب الصلاة 157

وَعَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم قَالَ: «مَنْ خَرَجَ مِنْ بَيْتِهِ مُتَطَهِّرًا إِلَى صَلَاةٍ مَكْتُوبَة فَأَجره كَأَجر الْحَاج الْمُحْرِمِ وَمَنْ خَرَجَ إِلَى تَسْبِيحِ الضُّحَى لَا يُنْصِبُهُ إِلَّا إِيَّاهُ فَأَجْرُهُ كَأَجْرِ الْمُعْتَمِرِ وَصَلَاةٌ عَلَى إِثْرِ صَلَاةٍ لَا لَغْوَ بَيْنَهُمَا كِتَابٌ فِي عليين» . رَوَاهُ أَحْمد وَأَبُو دَاوُد

He also reported God’s Messenger as saying, “If one goes out from his house to a stated prayer in a state of purity, his reward will be like that of the pilgrim in the sacred state; if one goes out to devotions in the forenoon, nothing else causing him to go out, his reward will be like that of him who performs the ‘umra ;1 and a prayer following another with no idle talk between them will be a deed recorded in llliyun ,”2 1. The little pilgrimage, consisting of the rites at the Ka’ba and the running between al-Safa and al-Marwa. 2. See Al-Qur’an, 83:18 ff. Ahmad and Abu Dawud transmitted it.
