رَبُّكُمْ أَعْلَمُ بِمَا فِي نُفُوسِكُمْ إِنْ تَكُونُوا صَالِحِينَ فَإِنَّهُ كَانَ لِلْأَوَّابِينَ غَفُورًا ﴿۲۵﴾ وَآتِ ذَا الْقُرْبَى حَقَّهُ وَالْمِسْكِينَ وَابْنَ السَّبِيلِ وَلَا تُبَذِّرْ تَبْذِيرًا ﴿۲۶﴾ إِنَّ الْمُبَذِّرِينَ كَانُوا إِخْوَانَ الشَّيَاطِينِ وَكَانَ الشَّيْطَانُ لِرَبِّهِ كَفُورًا ﴿۲۷﴾

﴾25﴿ Rabbukum a'lamu bimaa fee nufoosikum; in takoonoo saaliheena fa innahoo kaana lil awwaabeena Ghafoooraa
﴾26﴿ Wa aati zal qurbaa haqqahoo walmiskeena wabnas sabeeli wa laa tubazzir tabzeeraa
﴾27﴿ Innal mubazzireena kaanoo ikhwaanash shayaateeni wa kaanash shaytaanu li Rabbihee kafooraa

﴾25﴿ Your Lord knows best what is in your hearts. If you are sincere, then indeed Allah is Forgiving to those who repent
﴾26﴿ And give the relatives their due right, as well as to the needy and the traveler, and do not squander wealth wastefully
﴾27﴿ Indeed, those who wastefully spend are the brothers of the devils, and Satan is ever ungrateful to his Lord

[25] In this verse, there is an indication toward correcting one's intention in showing kindness to parents.
The meaning of “Ṣāliḥīn” (صَالِحِينَ) refers to those who are sincere in their intention when being kind to their parents.
“For indeed, He is ever Forgiving to those who often return to Him” (فَإِنَّهُ كَانَ لِلْأَوَّابِينَ غَفُورًا) — this points to the fact that these two qualities, being righteous (ṣāliḥīn) and oft-returning (awwābīn), must go together.
Awwāb refers to someone who repents from sin and, whenever they remember their sin, they seek forgiveness again.
Benefit: In an authentic hadith, it is mentioned that the Ṣalāt al-Awwābīn is at the time when the ground becomes so hot from the sun that it burns the feet of young camels — and that time is Duḥā (forenoon).
As for the widespread belief among people that Ṣalāt al-Awwābīn is the optional prayer after Maghrib — this is incorrect.
[26] After the right of parents, this verse mentions three other groups of people who have rights.
“Tabdhīr” (تَبْذِيرًا) refers to spending wealth in a manner that is without justification, even if it is just one rupee — such as spending on vows made for other than Allah, or spending on innovations and rituals.
[27] The waster (mubadhdhir) is the brother of Satan, because Satan calls people to falsehood, and the waster, through misuse of wealth, supports Satan’s cause.
Likewise, Satan is ungrateful to his Lord — and in the same way, the waster is also ungrateful. Thus, both resemble one another.
