Is the repentance of one who committed an abomination then repented, and returned to her sin again, then regretted and repented, accepted? And is she considered among the people of hypocrisy?

No matter how often the sin is repeated and repentance is repeated, it is accepted by the permission of Allah, "Indeed, Allah loves those who are constantly repentant." And turning away from repentance, under the pretext of fearing its non-acceptance, is a satanic trick, for Satan wishes to gain despair from you regarding repentance. It is obligatory to hasten to repent and cut off every forbidden relationship, avoid the causes of sin, block the paths leading to it, beware of following the footsteps of Satan, associate with righteous women, and frequently remember Allah and supplicate to Him.
