wa alaykom al salam
excuse me I dont very well in english
but generally islam Islam does not distinguish between the weak and strong in the penalty they are all equaly
That elderly person had must respected his age and not commit such a mistake
But I do not know if there is in hadeeth punishment over 80 or 100 lashes as a maximum
the equality in punishment for all peoples not found in many arabic counries as america also hadith said
وعنها رضي الله عنها أن قريشا أهمهم شأن المرأة المخزومية التي سرقت فقالوا : من يكلم فيها رسول الله صلى الله عليه و سلم ؟ فقالوا : من يجترئ عليه إلا أسامة بن زيد حب رسول الله صلى الله عليه و سلم . فكلمه أسامة فقال رسول الله صلى الله عليه و سلم : [ أتشفع في حد من حدود الله تعالى ؟ ] ثم قام فاختطب ثم قال : [ إنما أهلك من قبلكم أنهم كانوا إذا سرق فيهم الشريف تركوه وإذا سرق فيهم الضعيف أقاموا عليه الحد وأيم الله لو أن فاطمة بنت محمد سرقت لقطعت يدها ] متفق عليه.
651. `Aishah (May Allah be pleased with him) reported: The Quraish were much worried about the case of a Makhzumiyah woman who had committed theft and wondered who should intercede for her with Messenger of Allah (PBUH) (so that she would not get punished for her crime). Some said Usamah bin Zaid (May Allah be pleased with him) was his beloved and so he may dare do so. So Usamah(May Allah be pleased with him) spoke to him about that matter and the Prophet (PBUH) said to him, "Do you intercede when one of the legal punishments ordained by Allah has been voilated?'' Then he got up and addressed the people saying, "The people before you were ruined because when a noble person amongst them committed theft, they would leave him, but if a weak person amongst them committed theft, they would execute the legal punishment on him. By Allah, were Fatimah, the daughter of Muhammad, to commit the theft, I would have cut off her hand.''
[Al-Bukhari and Muslim].
Commentary: The example of Allah's Messenger (PBUH) clearly tells us that no intercession is allowed for a person who transgresses the limits set by Allah. And if anybody has the audacity to do so, the deciding authority is presumed to be impervious to his solicitation. Nor should the criminal's social status or family influence, if any, obstruct the administration of justice. The law and retribution rise above all discrimination and social hierarchy. Any contravention in this regard is enough to incur Divine wrath.
