حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عَبْدِ الْمَجِيدِ ، حَدَّثَنَا مَالِكٌ ، عَنْ نَافِعٍ ، عَنْ ابْنِ عُمَرَ رَضِيَ اللهِ عَنْهُمَا، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَكَرَ رَمَضَانَ، فَقَالَ :" لَا تَصُومُوا حَتَّى تَرَوْا الْهِلَالَ، وَلَا تُفْطِرُوا حَتَّى تَرَوْهُ، فَإِنْ غُمَّ عَلَيْكُمْ، فَاقْدُرُوا لَهُ "

If it is cloudy for you, prepare for it.”
