Is tavaf valid if one has a minor impurity (hadath asghar)?

The majority of scholars hold that abdest is a condition for the validity of tavaf, based on the hadith: 'Tavaf around the House is namaz, except that Allah has permitted speaking during it' (narrated by al-Hakim, authenticated by al-Albani). However, Sheikh Ibn Taymiyyah and Sheikh Ibn Uthaymeen held the opinion that abdest is sunnet but not a strict condition for tavaf validity. If a haci loses abdest during tavaf, the safer opinion is to renew abdest and resume from where the circuit was interrupted.
