you who have believed, when [the adhan] is called for the prayer on the

Al-Baqarah (The Cow) - سورة البقرة Chapter 2 Verse 278 - 279 O you who have believed, fear Allah and give up what remains [due to you] of interest, if you should be believers.

An-Nūr (The Light) - سورة النور Chapter 24 Verse 51 - 52 And whoever obeys Allah and His Messenger and fears Allah and is conscious of Him - it is those who are the attainers.

Al-Mā'idah (The Table Spread) - سورة المائدة Chapter 5 Verse 104 And when it is said to them, "Come to what Allah has revealed and to the Messenger," they say, "Sufficient for us is that upon which we found our fathers."

Our Lord, give them double the punishment and curse them with a great curse."
The Holy Quran Al-'Aĥzāb (The Combined Forces) -سورة الأحزاب Chapter 33 Verse 70-71

The Holy Quran Surat At-Tawbah (The Repentance) -سورة التوبة Chapter 9 Verse 36
Indeed, the number of months with Allah is twelve [lunar] months in the register of Allah [from] the day He created the heavens and the earth; of these, four are sacred. That is the correct religion, so do not wrong yourselves during them. And fight against the disbelievers collectively as they fight against you collectively. And know that Allah is with the righteous [who fear Him].
