question #3 Sahih al-Bukhari 6200, Book 78, Hadith 224 : What is the significance of invoking historical events, such as the famine during Prophet Yusuf’s time, in prayers for divine intervention?

When the Prophet (ﷺ) (once) raised his head after bowing [in the Salat (prayer)] he said, “O Allah, save Al-Walid bin Al-Walid and Salama bin Hisham and ‘Aiyyash bin Abu Rabi’a and the helpless weak believers of Makkah. O Allah, be hard on the tribe of Mudar. O Allah, send on them (famine-drought) years like the (famine-drought) years of (the Prophet) Yusuf (Joseph).”
