فِي رَجُلٍ صَامَ فِي ظِهَارٍ شَعْبَانَ ثُمَّ أَدْرَكَهُ شَهْرُ رَمَضَانَ قَالَ يَصُومُ شَهْرَ رَمَضَانَ ثُمَّ يَسْتَأْنِفُ الصَّوْمَ وَ إِنْ هُوَ صَامَ فِي الظِّهَارِ فَزَادَ فِي النِّصْفِ يَوْماً قَضَى بَقِيَّتَهُ.

Hadith.2006 - Mansur ibn Hazim narrated from Abu Abdullah (as) regarding a man who was fasting as expiation (for zihar) during Sha’ban and then Month of Ramadan began. Imam (as) said: "He should fast the Month of Ramadan and then resume the expiation fast. However, if he was fasting for expiation and completed half a day more than the midpoint (of the fast), he can simply complete the remaining days."
