عَنْ أُسَامَةَ بْنِ زَيْدٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: قُلْتُ: يَا رَسُولَ اللَّهِ! لَمْ أَرَكَ تَصُومُ مِنْ شَهْرٍ مِنَ الشُّهُورِ مَا تَصُومُ مِنْ شَعْبَانَ؟ قَالَ: ((ذَلِكَ شَهْرٌ يَغْفُلُ النَّاسُ عَنْهُ، بَيْنَ رَجَبٍ وَرَمَضَانَ، وَهُوَ شَهْرٌ يُرْفَعُ فِيهِ الْأَعْمَالُ إِلَى رَبِّ الْعَالَمِينَ، فَأُحِبُّ أَنْ يُرْفَعَ عَمَلِي وَأَنَا صَائِمٌ))
Sayyiduna Usama bin Zaid (may Allah be pleased with him) says: I said, "O Messenger of Allah! I have seen that you fast in the month of Sha'ban more than in any other month?" The Prophet (peace and blessings be upon him) said: "This is a month between Rajab and Ramadan that people are heedless of. It is a month in which the deeds of people are raised to the Lord of the worlds, and I wish that my deeds are taken up while I am fasting."
