Hadith 15603ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ النَّهْدِيِّ عَنْ مُحَمَّدِ بْنِ وَلِيدٍ عَنْ عُمَرَ بْنِ يَزِيدَ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) يَقُولُ إِنَّمَا يُكْرَهُ الْقِرَانُ فِي الْفَرِيضَةِ فَأَمَّا النَّافِلَةُ فَلا وَالله مَا بِهِ بَأْسٌ.
3. Ahmad ibn Muhammad has narrated from Muhammad ibn Ahmad al-Nahdiy from Muhammad ibn Walid ‘Umar ibn Yazid who has said the following: “I once heard abu ‘Abd Allah (a.s.), say, ‘Joining Tawaf is Makruh (detestable) only in the case of obligatory Tawaf; but in the case of optional Tawaf, by Allah it is not harmful.’”
