There is a Sahih hadith that Allah, the Most Merciful, has 100 parts of mercy out of which He has given 1 part to the creatures and kept 99 with Him. Now 100 is not infinite. But in some places I've seen people saying that Allah, The Most Merciful, has unlimited or infinite Mercy. Confused. Please help.
The hadith say: خلق الله مائة رحمة فوضع واحدة بين خلقه وخبأ عنده مائة إلا واحدة (Allah created one hundred (parts of mercy) and He distributed one amongst His creation and kept this one hundred excepting one with Himself (for the Day of Resurrection)) - Sahih Muslim (2752).
The emphasis is on the words, 'Allah created'. Meaning, it is not referring to His Essence of Mercy. It's referring to the 'created mercy', one of which will be used up in the Dunya and the rest which will be used up in the Akhirah.
Of course, Allah's Attribute of Mercy is eternal. His Mercy will never be (could never be) exhausted.
