Is there any connection between Allah’s Greatest Name (ism a’zam) and treatment?
Answer:
Yes!
Whatever is asked by means of the Greatest Name, Allah grants.
It is narrated from Sayyida Aisha (may Allah be pleased with her) that the Messenger of Allah ﷺ said, indeed:
اسم الله الأعظم فى هاتين الآيتين
The Greatest Name of Allah is in these two verses:
وَإِلَٰهُكُمْ إِلَٰهٌ وَاحِدٌ ۖ لَّا إِلَٰهَ إِلَّا هُوَ الرَّحْمَٰنُ الرَّحِيمُ
“And your God is One God; there is no deity except Him, the Most Merciful, the Especially Merciful.”
الم ﴿١﴾ اللَّهُ لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ ﴿٢﴾
Alif, Lam, Mim. Allah, there is no deity except Him, the Ever-Living, the Sustainer of [all] existence.
It is narrated from Sayyidna Anas (may Allah be pleased with him) that indeed a man made supplication and said:
اللهم إني أسألك بأن لك الحمد لا إله إلا أنت المنان، بديع السماوات والأرض، يا ذا الجلال والإكرام يا حي يا قيوم
“O Allah! I ask You by virtue of the fact that all praise is due to You, there is no deity but You, You are the Bestower, the Originator of the heavens and the earth, O Possessor of majesty and honour, O Ever-Living, O Self-Subsisting.”
The Prophet ﷺ said:
لقد دعا الله باسمه الأعظم الذى إذا دعي به أجاب و إذا سئل به أعطىٰ
“He has supplicated Allah by His Greatest Name, which when He is called upon by it, He answers, and when He is asked by it, He gives.”
It is narrated from Sayyidna Buraydah al-Aslami (may Allah be pleased with him) that indeed the Messenger of Allah ﷺ heard a man saying:
اللهم إني أسألك بأنك أنت الله، لا إله إلا أنت الأحد الصمد، الذى لم يلد ولم يولد، ولم يكن له كفوا أحد
O Allah! Surely I ask You by this bond: that indeed You are Allah, there is no true deity except You, You are the One and Self-Sufficient, who did not beget and was not begotten, and none is equal to Him.
The Prophet ﷺ said:
دعا الله باسمه الأعظم الذى إذا سئل به أعطى و إذا دعي به أجاب
“He has supplicated Allah by His Greatest Name, that when He is asked by it, He gives, and when He is called upon by it, He answers.”
It is narrated from Sayyidna Abu Umamah (may Allah be pleased with him) that indeed the Messenger of Allah ﷺ said:
إسم الله الأعظم فى سور من القرآن ثلاث، فى البقرة، و آل عمران، و طه
The Greatest Name of Allah is in three surahs of the Qur’an: Surah al-Baqarah, Surah Aal-e-Imran and Surah Taha.
Thus it is known that whatever is asked by means of the Greatest Name, whether it is for illness or for anything else, Allah the Exalted accepts it.
