It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) used to make this supplication: 'Allahumma amti'ni bi-sam'i wa basari, waj'alhuma al-waritha minni; Allahumma-nsurni 'ala 'aduwwi, wa arini fihi tha'ri' (O Allah, let me benefit from my hearing and my sight (throughout my life) and make them my heir; O Allah, help me against my enemy and grant me victory over him, so that I see my revenge on him with my own eyes). This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
