Daawood (David), may Allah exalt his mention:

Daawood, may Allah exalt his mention, supplicated Allah The Exalted as Allah The Exalted Says (what means): {And Daawood became certain that We had tried him, and he asked forgiveness of his Lord and fell down bowing [in prostration] and turned in repentance [to Allah].} [Quran 38: 24]

Abu Bakr, may Allah be pleased with him:

Abu Bakr, may Allah be pleased with him, the best of this nation after the Prophet, sallAllahu ‘alayhi wa sallam, asked the Prophet, sallAllahu ‘alayhi wa sallam, "O Messenger of Allah, teach me an invocation with which I may invoke Allah in my prayers.” The Prophet, sallAllahu ‘alayhi wa sallam, said: “Say, ‘Allahumma inni thalamtu nafsi thulman katheeran wa la yaghfir ath-thunoob illa ant; ighfir li maghfiratan min ‘indik wa irhamni, innaka anta Al-Ghafoor Ar-Raheem (O Allah, I have wronged my soul very much and none forgives the sins but You; so please bestow Your forgiveness and mercy upon me. No doubt, You are the Oft-Forgiving, the Most Merciful).’” [Al-Bukhari]

‘Umar, may Allah be pleased with him:

‘Umar, may Allah be pleased with him, said to the Prophet, sallAllahu ‘alayhi wa sallam, "O Messenger of Allah, ask forgiveness for me."

There are numerous righteous and devout people other than these, who used to seek the forgiveness of Allah The Almighty frequently; repentance was their banner, their request for forgiveness was their slogan, and they repeatedly turned to Allah The Almighty.
