عَنْ جَابِرِ بْنِ سَمُرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَعَلَى آلِهِ وَصَحْبِهِ وَسَلَّمَ يَأْمُرُنَا بِصِيَامِ عَاشُورَاءَ وَيَحُثُّنَا عَلَيْهِ وَيَتَعَاهَدُنَا عِنْدَهُ، فَلَمَّا فُرِضَ رَمَضَانُ لَمْ يَأْمُرْنَا وَلَمْ يَنْهَنَا عَنْهُ وَلَمْ يَتَعَاهَدْنَا عِنْدَهُ
It is narrated from Sayyiduna Jabir bin Samurah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) used to command us to fast on the Day of Ashura, encourage us to do so, and when this day approached, he would also draw our attention to it. But when the fasting of the month of Ramadan was made obligatory, he (peace and blessings be upon him and his family) neither commanded us regarding it, nor forbade us from it, nor drew our attention to the arrival of this day.
