ٱلْحَمْدُ لِلَّهِ رَبِّ ٱلْعَـٰلَمِينَ
Al-ḥamdu lillāhi rabbi'l-ʿālamīn.
2All praise is due to Allah, Lord of all the worlds.
The verse opens with al-ḥamd — definite, total — not merely thanks for what is given but praise for what He is. Al-Rāzī ties this directly to ↦ 1:1: the bismillāh names Him; al-ḥamd then renders Him His due.
A second reading places the lām of lillāh as the lām of istiḥqāq — entitlement — so the sentence does not describe a transaction but a fact of the universe.

— Honest questions
A few things people ask.
Is the Arabic text verified?
Yes. Our base text is the Madinah Mushaf, cross-checked against tanzil.net. We do not edit the rasm or the diacritical marks under any circumstance.
Which tafāsīr do you ship?
Sixty-seven — twelve in English and fifty-five in Arabic. Al-Ṭabarī, al-Qurṭubī, al-Rāzī, Ibn Kathīr, al-Saʿdī, al-Baghawī, the Jalālayn, Ibn ʿĀshūr, al-Shawkānī, and many more — each indexed verse-by-verse and filterable by language in the drawer.
Who owns the notes I write?
You do. Export everything as Markdown + PNG at any time. We don’t train models on your study notes.
How is multiplayer different from a Google Doc?
Verse blocks are atomic. You can’t accidentally chop an āyah in half mid-merge. Comments anchor to verse references, not to character offsets, so they survive any rewrite.
