repenting, there will be nothing but destruction. Remember! Life of this world is only for a few days, whereas, the life of the Hereafter is everlasting. Undoubtedly, successful is the one who repents of his sins sincerely and strives to make his afterlife better. Successful is the one who enters Paradise by acting upon the actions that bring about the pleasure of Allah Almighty and the beloved Prophet صَلَّى اللهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم. Allah Almighty says in Part 4, Surah Āl ꜤImrān, verse no. 185:          

فَمَنۡ زُحۡزِحَ عَنِ النَّارِ وَ اُدۡخِلَ الۡجَنَّۃَ فَقَدۡ فَازَ ؕ وَ مَا الۡحَیٰوۃُ الدُّنۡیَاۤ اِلَّا مَتَاعُ  الۡغُرُوۡرِ (۱۸۵)

So whomsoever was saved from the Fire and admitted to Paradise, indeed he succeeded; and the life of this world is merely a provision of deception.^[1]

It is stated in Tafsīr Ṣirāṭ al-Jinān, vol. 2, p. 112:

From this blessed verse, we come to know that true success on the Day of Judgement will be that a person is freed from Hell and entered into Paradise. Whereas, success of this world is success from its own perspective, but if this success is harmful for the afterlife, then it is a means of loss in reality. Moreover, those who do everything for the success of this world and nothing for the success of the Hereafter are certainly in loss. Therefore, every Muslim should focus and strive more for such actions that can bring him true success and refrain from those actions that become an obstacle in attaining it.
