Hadith 649B1

وَسُئِلَ مَالِك ، عَنْ رَجُلٍ دَخَلَ الْمَسْجِدَ لِعُكُوفٍ فِي الْعَشْرِ الْأَوَاخِرِ مِنْ رَمَضَانَ فَأَقَامَ يَوْمًا أَوْ يَوْمَيْنِ ، ثُمَّ مَرِضَ فَخَرَجَ مِنَ الْمَسْجِدِ أَيَجِبُ عَلَيْهِ أَنْ يَعْتَكِفَ مَا بَقِيَ مِنَ الْعَشْرِ إِذَا صَحَّ ، أَمْ لَا يَجِبُ ذَلِكَ عَلَيْهِ ، وَفِي أَيِّ شَهْرٍ يَعْتَكِفُ إِنْ وَجَبَ عَلَيْهِ ذَلِكَ ، فَقَالَ مَالِك : يَقْضِي مَا وَجَبَ عَلَيْهِ مِنْ عُكُوفٍ إِذَا صَحَّ فِي رَمَضَانَ أَوْ غَيْرِهِ
Imam Malik, may Allah have mercy on him, was asked: If a person begins i'tikaf in the last ten days of Ramadan, then after one or two days he becomes ill and leaves the mosque, should he make up the days that remained when he becomes healthy, or should he not make them up? And if he does make them up, in which month should he do so? Imam Malik, may Allah have mercy on him, replied: He should make up those days when he becomes well, whether in Ramadan or in any other month.
