When you need something to hold on to
What the Qur'an says it is for.
وَنُنَزِّلُ مِنَ ٱلْقُرْءَانِ مَا هُوَ شِفَآءٌ وَرَحْمَةٌ لِّلْمُؤْمِنِينَ ۙ وَلَا يَزِيدُ ٱلظَّـٰلِمِينَ إِلَّا خَسَارًا
Wa nunazzilu mina-l-qur'āni mā huwa shifā'un wa raḥmatun li-l-mu'minīn…
“And We send down of the Qur’ān that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss.”
