Questioning on the Day of Judgement

It is narrated from Abi Barzah that the Messenger of Allah (ص) said:

﴿ لَا تَزُولُ قَدَمَا عَبْدٍ حَتَی يُسْأَلَ عَنْ أَرْبَعَةٍ: عَنْ جَسَدِهِ فيمَا أَبْلَاهُ، وَعُمرِهِ فِيمَا أَفْنَاهُ، وَمَالِهِ مِنْ أَيْنَ اكْتَسَبَهُ وَفِيمَا أَنْفَقَهُ، وَعَنْ حُبِّ أَهْلِ الْبَيْتِ ﴾

فَقيلَ: يَا رَسُولَ اللهِ!، فَمَا عَلَامَةُ حُبِّكُمْ؟

فَـضَـرَبَ ـ صَلَّی ‌اللهُ ‌عَلَيْهِ ‌وَ آلِهِ ـ بِيَدِهِ عَلَی مِنْكَبِ عَلِيٍّ

"No servant will take any step forward unless he has been questioned about four things: About his body in which way he decayed it, about his age in which way he spent it, about his wealth from which way he acquired it and in which way he used it, and about his love for our Ahl al-Bayt» (whether emerged in his heart or not)."
It was asked: O Messenger of God! What is the sign of your love?
So he, (ص) placed his hand on Ali’s (ع) shoulder (who was standing near him).
