Quran 2:43 — The Heifer (Al-Baqarah)

You shall observe the Contact Prayers (Salat) and give the obligatory charity (Zakat), and bow down with those who bow down.

[2:42] Do not confound the truth with falsehood, nor shall you conceal the truth, knowingly.

[2:44] Do you exhort the people to be righteous, while forgetting yourselves, though you read the scripture? Do you not understand?
