I said, "Messenger of Allah, my sister has vowed to walk to the House barefoot and unveiled."The Prophet ﷺ replied, "Allah gains nothing from your sister's hardship. Let her ride, let her veil herself, and let her fast for three days."
قلت: يا رسول الله إن أختي نذرت أن تمشي إلى البيت حافية غير مختمرة. فقال النبي ﷺ: إن الله لا يصنع بشقاء أختك شيئا، فلتركب، ولتختمر، ولتصم ثلاثة أيام.
Abu Dawud (3294), Tirmidhi (1544), Nasai (3815), Ibn Majah (2134), and Bayhaqi (10/80) all narrated it, all through the hadith of Ubaydullah bin Zahr, from Abu Saeed Rueni, from Abdullah bin Malik Yahsabi, from Uqba bin Amir, who related it. Tirmidhi said, "This is a hasan hadith." I say, it contains Ubaydullah bin Zahr, who is daif, but he has been corroborated. Ahmad narrated it (17330) from Hasan, who said, Ibn Lahia told us, Bakr bin Sawada told us, from Abu Saeed, with the same wording. Bakr bin Sawada is trustworthy and a jurist, but the narrator from him, Ibn Lahia, has poor memory. Tahawi also narrated it in his Mushkil (2150) through the route of Abdul-Razzaq, who said, Ibn Jurayj informed us, who said, Saeed bin Abu Ayub told me, from Yazid bin Abu Habib, from Abu Khayr, from Uqba bin Amir, who related the hadith in similar fashion. Taken together, these routes make the hadith hasan.Tirmidhi said, "This is the practice among the people of knowledge, and it is the view of Ahmad and Ishaq." His statement, "and let her fast three days," is an addition that does not contradict what was stated unrestricted in the hadith of Uqba bin Amir. It may be that he first instructed her to sacrifice a camel, and if she was unable to do so, then to fast three days, thus reconciling the two narrations, except that the narrator abbreviated it, causing the reader to misunderstand.On this subject there is also what has been related from Uqba bin Amir, who said, I heard the Messenger of Allah ﷺ say, "A vow is like an oath, its expiation is the expiation of an oath." Imam Ahmad narrated this (17340) from Abu Saeed, the freedman of Banu Hashim, who said, Ibn Lahia told us, who said, Kaab bin Alqama told us, who said, I heard Abdul-Rahman bin Sahammasa say, We came to Abu Khayr, and he said, I heard Uqba bin Amir say, and then he related the hadith. Ibn Lahia has poor memory, but he is not problematic when used as a supporting witness.
