Performing طواف during rain is entirely permissible and is, in fact, considered a specially blessed time by scholars. There is no scholarly prohibition or dislike associated with طواف during rainfall. نبی کریم (صلی اللہ علیہ وسلم) identified rainfall as one of the times when دعا is more likely to be answered, making طواف during rain an excellent opportunity to combine two blessed acts — circumambulating the کعبۃ اللہ and supplicating during rainfall.
Sheikh Ibn Baz encouraged حجاج to take advantage of rain during their حج, noting that it is a manifestation of Allah's mercy and a time when the gates of heaven are opened. He stated there is no basis for the claim that طواف should be postponed due to rain. The Permanent Committee similarly confirmed that طواف during rain is valid and carries no special restrictions.
From a practical standpoint, scholars note that the Mataf (طواف area) can become slippery during rain, and حجاج — especially the elderly and those with mobility issues — should exercise caution. The مسجد الحرام administration takes measures to ensure safety during such times. Pilgrims may also perform طواف on the covered upper floors if they prefer to avoid the rain, and this is equally valid. Using an umbrella during طواف is also permissible.
