Wearing of the crown after one finishes hifz

Assalamu Alaikum Warahmatullahi Wabaraktu respected Muftisaab. How are you?

My question is as we all know when a youngster in the prime of his life completes his hifz while under the care of his parents, they (his parents) will be wearing crowns made of gold & jewels on the day of judgement due to their sacrifice, now my question is what if someone is in his/her later years as in above 25 years of age or married and living separately from his parents..who will get the reward of wearing the crown on the day of judgement after completing their hifz?

Hope this makes sense.

Shukran Jazakallah

Ma’asalaam.
