Abu Huraira (may Allah be pleased with him) reported that the Messenger of Allah (peace be upon him) said: When anyone of you leaves his house, he should say: Bismillah, tawakkaltu 'alallahi, wa la hawla wa la quwwata illa billah (In the name of Allah, I trust in Allah, and there is no might nor power except with Allah). Then it will be said to him: 'You are guided, you are sufficed, and you are protected.' And the devil will go far away from him, and another devil will say to him: 'How can you deal with a man who has been guided, sufficed and protected?' (In another narration) When one of you performs ablution and then sets out for the mosque, he is in the state of one who is in Ihram (state of consecration during Hajj or Umrah). And when he sits in the mosque until he performs the prayer, he is in the state of one who is praying. And when he goes out of the mosque and does not go back to it, he is in the state of one who is on a mission of war. And when he enters his house and does not enter the mosque, he enters his house in the state of one who has no good. This hadith highlights the immense reward associated with going to the Masjid. While the specific dua for leaving the Masjid mentioned in your request is not directly in this hadith, the context of seeking Allah’s bounty upon departure from a place of worship is consistent with the general principle of seeking Allah’s help in all affairs, especially when embarking on fulfilling commitments made to Him.
