Al Harith Al Ash`ary (may Allah be pleased with him) narrated that the Prophet said: “Allah (Glory be to Him) commanded Yahya ibn Zakariya to act according five words and command the children of Israel to act according to them, but he almost slowed down to convey them. Thereupon, Jesus said to him: Allah commanded you to act according five words and commanded you to command the children of Israel to act accordingly, so either you tell them or I will do so.
Yahya said: O brother, I am afraid if you preceded me, I will be tortured or sunk under the earth. He said: Yahya gathered the Children of Israel in Jerusalem until the Masjid was filled and people sat on the balconies of the Masjid. He praised Allah then said: Allah commanded me to act according five words and commanded you too to act according to them. The first is to worship Allah and associate none with Him in worship. This example is like a man bought a slave out of pure gold or silver, but that slave worked and the money he earned was given to other than his master, who would like that his slave is like that one?
Allah (Glory be to Him) created you and provided you sustenance, so worship Him and associate none with Him in worship. I command you with offering Salah because Allah (Glory be to Him) erect His Face before the face of His Servant as long as the servant does not look right or left, so when you offer Salah, do not look right or left. I command you with fasting, the likeness of that is like a man who has a bundle of musk among a group of people where all of them can find the smell of musk. Indeed, the bad smell of a fasting person is better in the sight of Allah than the smell of musk. I command you with charity, and the likeness of that is like a man captured by enemy who tied his hands to his neck and advanced him to be killed. Thereupon, he said: is there something I can do to ransom my life from you? He kept on ransoming himself from them by little and much until he could ransom himself. I command you to mention Allah (Glory be to Him) frequently; the likeness of that is like a man after whom the enemy were running, but he entered a fortified fort to save himself. A servant is more secure from Satan when he mentions the name of Allah (Glory be to Him). He (the narrator) said: The Messenger of Allah (peace be upon him) said: As for me, I command you with five things that Allah commanded me with: To be with Muslim group, to listen (to the orders), to obey (your leaders), to migrate, and to fight in the cause of Allah. He who abandons the Muslim group even for a hand-span, he will not be a Muslim until he comes back to Islam. And whoever does an act from the Pre-Islamic period will be from the people of Hell. They said: O Messenger of Allah, even if that person offered Salah and fasted (Ramadan)? Thereupon, the Prophet said: Even if that person offered Salah, fasted (Ramadan), and claimed to be a Muslim. So, call Muslims by their names which Allah (Glory be to Him) chose for them: Muslims, believers, and the servants of Allah (Glory be to Him).”(1)
The meaning of migration in this Hadith is moving from Makkah to Madinah before the opening of Makkah, from disbelief to Islam, from heresy to Sunnah, and from committing sins to repentance because of the Prophet’s saying: “And a Muhajir (emigrant) is the one who gives up (abandons) all what Allah has forbidden.” (3)
