Ibn 'Umar (R) was narrated. He said, Allah's Messenger Hazrat Muhammad (SM) said, "The pillar of Islam is five." 1. There is no god but Allah, and surely Muhammad (peace and blessings of Allaah be upon him) has testified to the Messenger of Allah. 2. Praying prayer. 3. Earning zakat. 4. Performing Hajj and 5 Ramadan fasting and fasting. (4514; Muslim 1/5 HH 16, Ahmad 6022, 6309) (Modern Publication: 7, Islamic Foundation: 7)
Allah says: "There is no virtue to turn your faces toward the east and the west; But if one believes in someone who believes in Allah, in the Hereafter, on the angels, on all the Books, and on all the Prophets, and if money is given to God, then Allah will love for relatives, orphans, destitute, traveler, help, and slave, If he has paid Zakat, and if he fulfills his promise and lacks patience, he is patient in disease and war. These are the true beings, and they are the righteous '' - (al-Baqarah 2/177). "Verily, those who believe are successful" - (Surah Mu'minun 23/1).
