[Machine] The Prophet Muhammad ﷺ used to encourage people to observe Ramadan without explicitly commanding them to do so. He would say, "Whoever observes Ramadan with faith and seeking reward will have their past sins forgiven." Abu Abdul Rahman Ishaq ibn Rashid said, "He is not the strongest in narration among Al-Zuhri and Musa ibn A'yan, but he is trustworthy."
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُرَغِّبُ النَّاسَ فِي قِيَامِ رَمَضَانَ مِنْ غَيْرِ أَنْ يَأْمُرَهُمْ بِعَزِيمَةِ أَمْرٍ فِيهِ فَيَقُولُ «مَنْ قَامَ رَمَضَانَ إِيمَانًا وَاحْتِسَابًا غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ» قَالَ أَبُو عَبْدِ الرَّحْمَنِ إِسْحَاقُ بْنُ رَاشِدٍ لَيْسَ بِذَاكَ الْقَوِيِّ فِي الزُّهْرِيِّ وَمُوسَى بْنُ أَعْيَنَ ثِقَةٌ
