DO NOT DO IT IF YOU DO NOT FALL DUE

Try to get something before the time came often will only bring losses. Logically, try to eat fruit which still not ripe is not relevent. 

Prophet Muhammad (pbuh) said:

مَنْ اسْتَعْجَلَ شَيْئاً قَبْلَ أَوَانِهِ عُوقِبَ بِحِرْمَانِهِ

Means: Whoever in a hurry before reaching term, would the consequences be prevented from get. (Al-Ashbah Wa An-Nazair, As-Sayuti, page 195)
