Belief in Allah
Belief in Allah is the root of every other belief. It means believing that Allah exists, and that He is One in everything that belongs to Him. Scholars often explain this oneness (tawhid) in three ways, which together describe a single faith.
First, He alone is the Lord: He alone creates, provides, gives life and death, and runs the affairs of all that exists. Second, He alone deserves worship: prayer, supplication, reliance, hope and fear are directed to Him and to no one else, as every Muslim says in al-Fatihah, ﴿إِيَّاكَ نَعْبُدُ وَإِيَّاكَ نَسْتَعِينُ﴾ (“You alone we worship, and You alone we ask for help”) (1:5). Third, He has the most beautiful names and perfect attributes (7:180). We affirm what Allah and His Messenger ﷺ have told us about Him, without likening Him to His creation and without denying what He has affirmed, for ﴿لَيْسَ كَمِثْلِهِۦ شَىْءٌ ۖ وَهُوَ ٱلسَّمِيعُ ٱلْبَصِيرُ﴾ (“There is nothing like Him, and He is the All-Hearing, the All-Seeing”) (42:11).
Surat al-Ikhlas sums this up in four short verses, and the Prophet ﷺ taught that Allah has ninety-nine names, and that whoever learns them by heart will enter Paradise (Sahih al-Bukhari 7392). Belief in Allah shapes a believer's whole life: it frees the heart from depending on anyone but Him, gives meaning to hardship and blessing alike, and turns every good deed into worship.
قُلْ هُوَ ٱللَّهُ أَحَدٌ ﴿١﴾ ٱللَّهُ ٱلصَّمَدُ ﴿٢﴾ لَمْ يَلِدْ وَلَمْ يُولَدْ ﴿٣﴾ وَلَمْ يَكُن لَّهُۥ كُفُوًا أَحَدٌۢ ﴿٤﴾
Qul huwa Allahu ahad. Allahu al-samad. Lam yalid wa lam yulad. Wa lam yakun lahu kufuwan ahad.
Say: He is Allah, the One. Allah, the Self-Sufficient, whom all depend on. He does not beget, nor was He begotten. And there is none comparable to Him.

What the hadith grades mean
- Sahih (authentic): an unbroken chain of trustworthy, precise narrators, free of hidden flaws or contradiction. It is acted upon.
- Hasan (good): like sahih, but a narrator's precision is slightly lighter. It is also accepted and acted upon. "Hasan sahih" means it reaches sahih by its routes.
- Da'if (weak): a break in the chain or a narrator who is not reliable enough. It is not used to establish beliefs or rulings.
- Very weak (munkar, matruk): a seriously flawed chain or a narrator accused of lying. It is not relied on at all.
- Mawdu' (fabricated): falsely attributed to the Prophet ﷺ. It may not be narrated as his words except to warn against it.
- The two Sahihs: every hadith with a full chain in Sahih al-Bukhari and Sahih Muslim is accepted as sahih by the scholars of hadith.
- Historical report: biographies and histories (Ibn Ishaq, Ibn Sa'd, al-Tabari) record events with chains that are often incomplete. They are used for the story, not for rulings.
- Hadith scholars grade a narration; the four madhhabs do not. Where a hadith carries a ruling, the page shows which schools act on it.
