(حديث مرفوع) حَدَّثَنَا وَكِيعٌ ، حَدَّثَنِي سَلَمَةُ بْنُ وَرْدَانَ ، قَالَ : سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِأَصْحَابِهِ ذَاتَ يَوْمٍ : " مَنْ شَهِدَ مِنْكُمْ الْيَوْمَ جَنَازَةً ؟ ، قَالَ عُمَرُ أَنَا ، قَالَ : مَنْ عَادَ مِنْكُمْ مَرِيضًا ؟ ، قَالَ عُمَرُ : أَنَا ، قَالَ : مَنْ تَصَدَّقَ ؟ ، قَالَ عُمَرُ : أَنَا ، قَالَ : مَنْ أَصْبَحَ صَائِمًا ؟ ، قَالَ عُمَرُ : أَنَا ، قَالَ : وَجَبَتْ ، وَجَبَتْ " .
It is narrated from Hazrat Anas (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) asked his companions (may Allah be pleased with them), "Who among you has attended a funeral today?" Hazrat Umar (may Allah be pleased with him) presented himself. Then the Prophet (peace and blessings be upon him) asked, "Has anyone among you visited a sick person?" Hazrat Umar (may Allah be pleased with him) replied, "I have." Then he asked, "Has anyone given charity?" Hazrat Umar (may Allah be pleased with him) again presented himself. Then he asked, "Has anyone fasted today?" Hazrat Umar (may Allah be pleased with him) replied, "I have fasted." The Prophet (peace and blessings be upon him) said twice, "It has become obligatory."
