Question: Some new Muslims, when their being prompted to recite the Shahadah [to enter Into Islam], are not able to pronounce it properly?
Answer: “There is no harm in this due to His statement, the Exalted:
لاَ يُكَلِّفُ اللَّهُ نَفْسًا إِلاَّ وُسْعَهَا
Allah burdens not a person beyond his scope [2:286]”
[Fataawa Su’aal ‘alal-Haatif (2/699)]
