What does it mean to call upon Allah by His Names?
Allah revealed: 'And to Allah belong the best names, so invoke Him by them' (Qur'an 7:180), and: '[He is] Allah, there is no deity except Him. To Him belong the best names' (Qur'an 20:8). Calling on Allah by His Names means matching the Name to the need: ask the Most Merciful (Ar-Rahman, Ar-Rahim) for mercy, the Forgiver (Al-Ghafur) for forgiveness, the Healer (Ash-Shafi) for healing, the Sustainer (Ar-Razzaq) for sustenance. The Prophet, peace be upon him, said Allah has ninety-nine names; one who 'counts' them (memorises, understands, and acts on them) enters paradise (Sahih al-Bukhari 2736, Sahih Muslim 2677). The list-enumeration in some narrations is graded weak (Jami' at-Tirmidhi 3507); the count of ninety-nine itself stands.
Is there a single greatest Name of Allah?
Yes - the Sunnah indicates Allah has a Greatest Name (Ism al-A'zam) which, when invoked, He answers. The Prophet, peace be upon him, taught a formula in Sunan Abi Dawud 1493: 'O Allah, I ask You by my testimony that You are Allah, there is no deity but You, the One, the Self-Sufficient, who neither begets nor was begotten, and to whom none is equal' - and said the supplicant asked Allah by His Greatest Name, with which when called He answers, and when supplicated He gives. The narration also indicates the Greatest Name lies in three surahs: Al-Baqarah, Aal-Imran, and Ta-Ha. The believer recites this formula at moments of urgent need, after fard salah, or in the last third of the night.
Can I make up a praise-name for Allah that is not in the Qur'an?
No. The Names of Allah are tawqifi - established by revelation, not invented by humans. Allah revealed: 'And to Allah belong the best names, so invoke Him by them. And leave [the company of] those who practice deviation concerning His names' (Qur'an 7:180) - the warning against 'deviation' (ilhad) covers both denying His established Names and adding names He did not give Himself. Use the Names attested in the Qur'an and authentic Sunnah. Generic praise ('You are the Most High,' 'You are the Source of all good') is acceptable as description; coining a proper Name (Al-X, with the definite article) requires textual basis.
?Are the 99 Names of Allah only 99, or are there more?
There are more. The Prophet, peace be upon him, said Allah has ninety-nine names that, if counted, lead to paradise (Sahih al-Bukhari 2736, Sahih Muslim 2677). But other authentic narrations show the Prophet asked Allah by Names he said only Allah knows or has reserved for Himself. The ninety-nine is a special category - the names whose counting leads to paradise - not a cap on the total. Allah's Names are infinite in the sense that they include any beautiful praise that exists in His knowledge and we have not been told of.
?Should I read 99-name lists I find on the internet?
Verify the list first. The specific enumeration of all 99 names in a single hadith is graded Da'if (Jami' at-Tirmidhi 3507); the names themselves are found scattered across Qur'an and authentic Sunnah, but the particular 99-item list circulating online is the work of scholars (Ibn Hajar, Ibn al-Uthaymin) compiling textual mentions, not a single revealed list. Use lists from trusted scholarly sources (Bin Baz, Ibn al-Uthaymin) where each Name has its textual basis cited. Avoid lists that include unverified names with no Qur'anic or hadith source.
