Understandably, you should get baptized only when you are qualified to make that decision, you have a personal desire to do so, and you understand the meaning of dedication. What if you are not sure that you are ready for baptism?
لِذٰلِكَ قَبْلَ أَنْ تَعْتَمِدَ ،‏ يَجِبُ أَنْ تَكُونَ نَاضِجًا كِفَايَةً ،‏ تَتَأَكَّدَ أَنَّ قَرَارَكَ نَابِعٌ مِنْ قَلْبِكَ ،‏ وَتَفْهَمَ مَعْنَى ٱلِٱنْتِذَارِ .‏
