Abdullah bin Masud reported,

The Messenger of Allah ﷺ, when delivering the tashahhud, would say, "Praise be to Allah. We seek His help and His forgiveness, and we seek refuge in Allah from the evils of our souls. Whomever Allah guides, none can lead astray, and whomever He leads astray, none can guide. I bear witness that there is no god but Allah, and I bear witness that Muhammad is His servant and His messenger, whom He sent with the truth as a Bashir of glad tidings and a warner before the Hour. Whoever obeys Allah and His Messenger has been rightly guided, and whoever disobeys them harms only himself and does no harm to Allah at all."

حدثنا محمد بن بشار حدثنا أبو عاصم حدثنا عمران عن قتادة عن عبد ربه عن أبي عياض

عن ابن مسعود

أن رسول الله ﷺ كان إذا تشهد قال الحمد لله نستعينه ونستغفره ونعوذ بالله من شرور أنفسنا من يهده الله فلا مضل له ومن يضلل فلا هادي له وأشهد أن لا إله إلا الله وأشهد أن محمدا عبده ورسوله أرسله بالحق بشيرا ونذيرا بين يدي الساعة من يطع الله ورسوله فقد رشد ومن يعصهما فإنه لا يضر إلا نفسه ولا يضر الله شيئا
