How can the Muslim begin to seek knowledge?

Indeed all the praises are due to Allah, we praise him and we seek his assistance and forgiveness, and we seek refuge in Allah from the evil of ourselves and our bad deeds, whoever Allah guides there is none that can misguide him and whoever is leads astray there is none that can guide him, and I bear witness there is no God other than Allah, He has no partners, and I bear witness that Muhammad is his servant and messenger.

O you who believe! Fear Allah as He should be feared. And die not except in a state of Islam. {Al-Imran:102}

O mankind! Be dutiful to your Lord, Who created you from a single person (Adam), and from him (Adam) He created his wife [Hawwa (Eve)], and from them both He created many men and women and fear Allah through Whom you demand your mutual (rights), and (do not cut the relations of) the wombs (kinship). Surely, Allâh is Ever an All-Watcher over you. {An-Nisa’:1}

O you who believe! Keep your duty to Allah and fear Him, and speak (always) the truth. He will direct you to do righteous good deeds and will forgive you your sins. And whosoever obeys Allah and His Messenger (SAW) he has indeed achieved a great achievement. {Al-Ahzaab:70&71}]

For verily the best of speech is the book of Allah and the best of guidance is the guidance of the Messenger. And beware of newly invented matters for every newly invented matter is a Bid’ah and every Bid’ah is misguidance and all misguidance is in the hellfire.

How can the Muslim begin to seek knowledge?
A Muslim seeker of knowledge should start with the Quran,
1)Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said:
There is no book better than the Book of Allah, may He be glorified and exalted. What I advise my brothers to do is to focus on the Holy Qur’an, memorising it, understanding it and acting upon it, for the Sahaabah (may Allah be pleased with them) did not go beyond ten verses until they had learned them and what they contain of knowledge and prescribed actions; they learned knowledge and put it into practice at the same time.
