Shakal bin Humaid (May Allah be pleased with him) reported:
I asked: "O Messenger of Allah, teach me a prayer." He (ﷺ) said, "Say: Allahumma inni a'udhu bika min sharri sam'i, wa min sharri basari, wa min sharri lisani, wa min sharri qalbi, wa min sharri maniyyi (O Allah! I seek refuge in You from the evils of my hearing, the evils of my seeing, the evils of my tongue; the evils of my heart and the evils of passions)."[Abu Dawud and At- Tirmidhi].
