Hadith: Whoever keeps on performing four Rak‘ahs before Zhuhr prayer and four after it, Allah will make the Fire forbidden for him

عن أم حبيبة رضي الله عنها مرفوعًا: «من حَافَظ على أربع رَكعات قبل الظهر وأربع بعدها حَرَّمَه الله على النَّار».
[صحيح] - [رواه الترمذي وأحمد وأبو داود والنسائي وابن ماجه]

Umm Habībah (may Allah be pleased with her) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Whoever observes the practice of performing four Rak‘ahs before Zhuhr prayer and four after it, Allah will make the Fire forbidden for him."
Sahih/Authentic. - [Ibn Maajah]

Explanation

The Hadīth indicates that anyone who regularly performs four Rak‘ah before Zhuhr prayer and another four after it, Allah, the Almighty, will reward him by preventing him from entering the Hell-fire. Other versions of this narration say: "Allah will prevent his flesh from touching Hellfire", or "The Fire shall not touch him." The Hadīth reported by Umm Habībah (may Allah be pleased with her) states the prohibition of Hellfire for him. So the fire will not touch or come close to the one continuously performs four Rak‘ahs before and after Zhuhr prayer out of Allah's bounty.
