Bismillahirrahmanirrahim

✦ Al Quran : The believers are only those who, when Allah is mentioned, feel a fear in their heartsand when His Verses (this Qur'an) are recited unto them, they increase their Faith, And they put their trust in their Lord (Alone); Who perform As-Salat (Iqamat-as-Salat) and spend out of that We have provided them. 

It is they who are the believers in truth. For them are grades of dignity with their Lord, and Forgiveness and a generous provision (Paradise). 

Al Quran, Surah Anfal 8, Verse: 2-4 

✦ Hadith: Narrated by Abu hurairah Radi Allahu Anhu The Prophet Peace be upon him said ALLAH will give shade to seven (types of people) under His Shade (on the Day of Resurrection). (one of them will be) a person who remembers ALLAH and his eyes are then flooded with tears.
