No. Don't hurt your parents in any way but don't cut off with any of your relatives, because it is a major sin to cut off with any relative. Try to do it tactfully to perform your duties towards your parents as well as towards your relatives. Obeying your parents can not allow disobeying Allah Who orders having good relation with all your relatives.

Tabarra is called in Arabic التبري من أعداء الله which means complete boycott and disassociation from the enemies of Allah (SWT) who are also enemies of the Prophet (SAWA) and Ahlul Bayt (AS). Tabarra is mentioned in Quran in many places and one whole Sura in Quran (Sura Tawbah) starts with Tabarra براءة من الله ورسوله.

Tabarra is the faith and practice of all the Prophets as we read in Quran in Sura 9, verse 114 ; (When it became clear for him (Ibraheem) that he (his uncle) is enemy of Allah, he disassociated himself from him).

Tabarra is one of the obligatory duties in Islam and no Muslim is permitted to have in his heart love of Allah and love of enemies of Allah at the same time.

We must be fully with Allah and His humble servants and totally against the enemies of them.

We must be careful when we express our feelings against the enemies of Allah (SWT), the Prophet (SAWA) and Ahlul Bayt (AS) not to instigate enmity with other communities as Allah orders us in Quran not to insult those are been worshipped besides Allah lest they wrong about Allah with no knowledge.

The authentic Hadeeth in al-Kaafi encourages kissing the hands of the Prophet (SAWA) and his Holy Progeny and any one whose hands are kissed for the sake of them. No doubt, kissing the hands of your parents is very good and also the hands of pious scholars who are servants of Ahlul Bayt (AS) and the hands of any believer as far as this kissing his hand is for the sake of Allah and not for worldly matter.

If you keep the gift unused to gift it to others, there is Khums on you as far as you give it others before completing one year from owning it. If one complete year passes and the gift is unused and belongs to you,bayou will then to pay the Khums of its current value of 20% of the material itself.
