Myself and team of musjidulhaq.com consulted the sharah of Bukhari Shareef by Allamah Ghulam Rasul Saeedi Alayhirahma and he also quotes from UMDATUL QARI, for a better understanding of this hadith, we came to the conclusion that the english translation we are presented with is misleading or it could be stated in a better manner. We ( musjidulhaq.com )thus translate the hadith as follows: " Narrated Al-Qasim bin Muhammad: `Aisha, (complaining of headache) said, "Oh, my head"! Allah's Messenger (ﷺ) said, "If it happens while I am still living (i.e. if you pass away during my lifetime) then I would ask Allah's Forgiveness for you and pray for you." Aisha said, "Wa thuklayah! By Allah, I think you want me to die; and If this should happen, you would spend the last part of the day as a groom with one of your wives!" The Prophet (ﷺ) said, "Nay, I should say, 'Oh my head!' I felt like sending someone to call Abu Bakr and his son, and appoint him as my successor lest some people claimed something or some others wished something, but then I said (to myself), 'Allah would not allow it to be otherwise, and the Muslims would prevent it to be otherwise"."
