Should Women Trot during Tawaf or Sa`i?
Question

Should a woman trot in Tawaf or between the two green markers in Sa`i between As-Safa and Al-Marwah, as men do?
Praise be to Allah.The Standing Committee for Academic Research and Issuing Fatwas said:
“Ibn Al-Mundhir said: The scholars unanimously agree that women do not have to trot around the Ka`bah or between As-Safa and Al-Marwah , and they do not have to uncover one shoulder , because the purpose behind these two actions is to show strength, and women are not included in that because the basic principle for women is to conceal themselves, but in trotting and baring one shoulder they would be uncovering themselves. 
And Allah is the Source of strength. May Allah send blessings and peace upon our Prophet Muhammad and his family and companions.” (Shaykh `Abd Al-`Aziz ibn `Abdulah ibn Baz, Shaykh `Abd Ar-Razzaq `Afifi, Shaykh `Abdullah ibn Ghadyaan and Shaykh `Abdullah ibn Qa`ud, Fatawa Al-Lajnah, 11/226-227)
