being fully halal. He was once invited to eat by someone who respected him. He accepted the invitation seeking to make the host happy. He took a bite of food and chewed it, but for some reason, could not swallow it. After some time, he took the food out of his mouth. It was later found out that there was some doubt as to whether the food was halal or haram.^[1]

Like this, many other saints were given ability to identify whether certain foods were haram or had doubt in their permissibility.

Do not become like the hard-hearted

Allah declares in His Quran:

وَ لَا یَکُوۡنُوۡا کَالَّذِیۡنَ اُوۡتُوا الۡکِتٰبَ مِنۡ قَبۡلُ فَطَالَ عَلَیۡہِمُ  الۡاَمَدُ فَقَسَتۡ قُلُوۡبُہُمۡ ؕ

 And they (the Muslims) should not become like those who were given the Book before and when the term was prolonged upon them, their hearts therefore became hard.^[2]

In this verse, Allah describes how previous nations were given a holy Book, yet their hearts still became hard from fleeting and unrealistic hopes. He instructs Muslims to not be like these previous People of the Book, to not have unrealistic hopes and to safeguard their hearts.

The gravest of all punishments

In a hadith narrated in Jāmiʿ al-Tirmidhi, the final Prophet صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, اِنَّ اَبْعَدَ النَّاسِ عَنِ اللَّهِ الْقَلْبُ الْقَاسِي - “The hard-hearted is the furthest of people from Allah.”^[3]
