Hadith: The miser is the one in whose presence I am mentioned, but he does not invoke Allah's blessings upon me

عَنِ الحُسَينِ بنِ عَلِيٍّ بنِ أَبِي طَالِبٍ رضي الله عنهما قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ:
«الْبَخِيلُ مَنْ ذُكِرْتُ عِنْدَهُ فَلَمْ يُصَلِّ عَلَيَّ».
[صحيح] - [رواه الترمذي والنسائي في الكبرى وأحمد] - [السنن الكبرى للنسائي: 8046]

Al-Husayn ibn ‘Ali ibn Abi Tālib (may Allah be pleased with him and his father) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said:
"The miser is the one in whose presence I am mentioned, but he does not invoke Allah's blessings upon me."
[Authentic hadith] - - [Major Sunan of An-Nasa'i - 8046]

Explanation

The Prophet (may Allah's peace and blessings be upon him) warned against refraining from invoking Allah's blessings upon him upon hearing his name, nickname, or description. He said: The complete miser is the one in whose presence I am mentioned, but he does not invoke Allah's blessings upon me. This is justified because:
First: He acted stingily regarding something that would not cause him to lose anything small or big and would not require him to spend money or exert effort.
Second: He acted stingily regarding himself as he deprived it of the reward of invoking Allah's blessings upon His Messenger (may Allah's peace and blessings be upon him) because by refraining from this, he withheld a right that he is required to fulfill in compliance with the command and a means of attaining a reward.
Third: Invoking Allah's blessings upon him fulfills part of the Prophet's right, as he is the one who taught us, guided us, called us to Allah Almighty, and brought us this revelation and this Shariah. In other words, he is the cause of our guidance after Allah Almighty. So, the one who does not invoke Allah's blessings upon him is stingy with himself and with his Prophet (may Allah's peace and blessings be upon him), as he withholds one of his simplest rights.
