التَّائِبُونَ الْعَابِدُونَ الْحَامِدُونَ السَّائِحُونَ الرَّاكِعُونَ السَّاجِدُونَ الْآمِرُونَ بِالْمَعْرُوفِ وَالنَّاهُونَ عَنِ الْمُنكَرِ وَالْحَافِظُونَ لِحُدُودِ اللَّهِ وَبَشِّرِ الْمُؤْمِنِينَ ١١٢

وَالْحَافِظُونَ wal-ḥāfiẓūna · and those who observe

[Such believers are] the repentant, the worshippers, the praisers [of Allāh], the travelers [for His cause], those who bow and prostrate [in prayer], those who enjoin what is right and forbid what is wrong, and those who observe the limits [set by] Allāh. And give good tidings to the believers. (Surah At-Tawbah, 9:112)

أَرْسِلْهُ مَعَنَا غَدًا يَرْتَعْ وَيَلْعَبْ وَإِنَّا لَهُ لَحَافِظُونَ ١٢

لَحَافِظُونَ laḥāfiẓūna · (will) surely (be) guardians

Send him with us tomorrow that he may eat well and play. And indeed, we will be his guardians." (Surah Yusuf, 12:12)

مَّن يُطِعِ الرَّسُولَ فَقَدْ أَطَاعَ اللَّهَ وَمَن تَوَلَّىٰ فَمَا أَرْسَلْنَاكَ عَلَيْهِمْ حَفِيظًا ٨٠

حَفِيظًا ḥafīẓan · (as) a guardian

He who obeys the Messenger has obeyed Allāh; but those who turn away - We have not sent you over them as a guardian. (Surah An-Nisa, 4:80)

الرِّجَالُ قَوَّامُونَ عَلَى النِّسَاءِ بِمَا فَضَّلَ اللَّهُ بَعْضَهُمْ عَلَىٰ بَعْضٍ وَبِمَا أَنفَقُوا مِنْ أَمْوَالِهِمْ فَالصَّالِحَاتُ قَانِتَاتٌ حَافِظَاتٌ لِّلْغَيْبِ بِمَا حَفِظَ اللَّهُ وَاللَّاتِي تَخَافُونَ نُشُوزَهُنَّ فَعِظُوهُنَّ وَاهْجُرُوهُنَّ فِي الْمَضَاجِعِ وَاضْرِبُوهُنَّ فَإِنْ أَطَعْنَكُمْ فَلَا تَبْغُوا عَلَيْهِنَّ سَبِيلًا إِنَّ اللَّهَ كَانَ عَلِيًّا كَبِيرًا ٣٤

حَفِظَ ḥafiẓa · (orders) them to guard

Men are in charge of women by [right of] what Allāh has given one over the other and what they spend [for maintenance] from their wealth. So righteous women are devoutly obedient, guarding in [the husband's] absence what Allāh would have them guard. But those [wives] from whom you fear arrogance - [first] advise them; [then if they persist], forsake them in bed; and [finally], strike them [lightly]. But if they obey you [once more], seek no means against them. Indeed, Allāh is ever Exalted and Grand. (Surah An-Nisa, 4:34)

حَافِظُوا عَلَى الصَّلَوَاتِ وَالصَّلَاةِ الْوُسْطَىٰ وَقُومُوا لِلَّهِ قَانِتِينَ ٢٣٨

حَافِظُوا ḥāfiẓū · Guard strictly

Maintain with care the [obligatory] prayers and [in particular] the middle [i.e., ʿaṣr] prayer and stand before Allāh, devoutly obedient. (Surah Al-Baqarah, 2:238)

اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ لَا تَأْخُذُهُ سِنَةٌ وَلَا نَوْمٌ لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ مَن ذَا الَّذِي يَشْفَعُ عِندَهُ إِلَّا بِإِذْنِهِ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلَا يُحِيطُونَ بِشَيْءٍ مِّنْ عِلْمِهِ إِلَّا بِمَا شَاءَ وَسِعَ كُرْسِيُّهُ السَّمَاوَاتِ وَالْأَرْضَ وَلَا يَئُودُهُ حِفْظُهُمَا وَهُوَ الْعَلِيُّ الْعَظِيمُ ٢٥٥

حِفْظُهُمَا ḥif'ẓuhumā · (the) guarding of both of them

Allāh - there is no deity except Him, the Ever-Living, the Self-Sustaining. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursī extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great. (Surah Al-Baqarah, 2:255)
