Someone asked “What are the indications if Allah has blessed someone with an accepted hajj (hajj mabrur)?” on SunniPath.com. Here’s what Faraz Rabbani anwsered:
The central and most significant sign of an accepted hajj (hajj mabrur) is that “one return better than one was before,” as Ibn al-Humam explains in Fath al-Qadir. [3.182] The same is mentioned by Mawardi in Adab al-Dunya wa’l Din, and by Ibn Abidin in Radd al-Muhtar.
This helps one understand why the Messenger of Allah (peace and blessings be upon him) said, “The accepted hajj has no reward but Paradise.” [Ahmad, and Tabarani in his Awsat, with a sound chain, and others]
And Allah alone gives success.
