← Previous Hadith “When the Messenger of Allah (ﷺ) raised his head from Ruku’ in the Subh prayer, he said: ‘O Allah, save Al-Walid bin Walid, Salamah bin Hisham and ‘Ayyash bin Abu Rabi’ah, and the oppressed in Makkah. O Allah, tighten Your grip on Mudar, and send them years of famine like the famine of Yusuf.”

Sunan Ibn Majah Book 5, Hadith 442 Next Hadith → “The Prophet (ﷺ) was stung by a scorpion while he was performing prayer, and he said: ‘May Allah curse the scorpion, for it does not spare anyone, whether he is praying or not. Kill them whether you are in Ihram or not.’” In Al-Hill (outside the sacred precincts of Makkah) or Al-Haram (the sacred precincts or Makkah).
