Converts enjoy the blessing that Hac erases all previous sins; join a knowledgeable group, do not hesitate to ask questions, and know that dua can be made in any language.
New Muslims performing Hac have a particularly blessed opportunity — Hz. Peygamber (sallallahu aleyhi ve sellem) said to Amr ibn al-As: 'Do you not know that Islam erases what came before it, and that Hijrah erases what came before it, and that Hac erases what came before it?' (Muslim). This means a convert performing Hac returns with a completely clean slate, all previous sins forgiven.
Practical advice for converts: join a reputable Hac group with an English-speaking (or your language) scholar who can guide you through rituals step by step. Do not feel embarrassed about asking questions — the companions themselves constantly asked Hz. Peygamber about Hac details. Learn the basic Arabic phrases for the rituals (Telbiye, takbir, key duas) but know that dua can be made in any language. If you do not have Muslim family, the Hac group becomes your spiritual family. Many converts report that Hac is where they truly feel the unity of the ummah, standing shoulder to shoulder with Muslims from every background. Your unique perspective as someone who chose Islam consciously is valuable and respected.
