Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) used to say: «اللهم متعني بسمعي وبصري، واجعلهما الوارث مني، وانصرني على عدوي، وأرني منه ثأري» "O Allah! Benefit me through my hearing and my sight, make them my inheritors, help me against my enemy, and show me retribution from him."
