Is reciting the Qur’an and dedicating its reward to a girl who committed suicide, reciting Surat Ya-Sin for her intercession, and supplicating for her forgiveness at her grave considered good for her?

Supplicating for the deceased, seeking forgiveness for them, and dedicating the reward of good deeds such as charity and reciting the Quran are all permissible. However, reciting the Quran at the grave was not done by the Prophet, peace be upon him, nor by his Rightly Guided Caliphs. As for women visiting graves, it is disliked by the majority of scholars, and some have even deemed it forbidden. Regarding the recitation of Surat Yasin for the deceased, no authentic hadith (definition) has been reported concerning it.
