Chapter 31 | The Meaning of “In the Name of Allah, the Most Compassionate, the Most Merciful”
2 - حدثنا أبي رحمه الله، قال: حدثنا سعد بن عبد الله، عن أحمد بن محمد، عن القاسم بن يحيى، عن جده الحسن بن راشد، عن عبد الله بن سنان، قال: سألت أبا عبد الله عليه السلام عن بسم الله الرحمن الرحيم، فقال: الباء بهاء الله، والسين سناء الله والميم مجد الله. وروي بعضهم: ملك الله، والله إله كل شئ، الرحمن بجميع خلقه، والرحيم بالمؤمنين خاصة.
2. My father said: Sa`d ibn `Abd Allah said, on the authority of Ahmad ibn Muhammad, on the authority of al-Qasim ibn Yahya, on the authority of his grandfather al-Hasan ibn Rashid, on the authority of `Abd Allah ibn Sinan that I asked Abut `Abd Allah al-Sadiq about the meaning of Bismillah al-Rahman alRahim; hence, he responded, The Ba * is the brilliance {baha] of Allah. The sin * is the splendor [sama] of Allah. The mim * is the magnificence [majd] of Allah, and some have related that it is the Kingdom [mulk] of Allah. Allah is the God of Everything. AlRahman is the Beneficent to all His creation, an al-Rahim is the One who is Merciful to the Believes specifically.
