She wants to convert to Islam but there are only men in the Islamic centre

Praise be to Allah.

Firstly, we want to congratulate you for seriously thinking about embracing Islam and entering into the true religion. May you be one of those for whom Allaah wishes good and whom He decrees will be one of those who enjoy happiness. Allaah says (interpretation of the meaning):

“And whomsoever Allaah wills to guide, He opens his breast to Islam…” [al-An’aam 6:125]

Secondly, it is not obligatory to declare your Islam at an Islamic centre, although this may be useful for some official purposes or if you need written proof of your Islam in the future. On this basis, it will be enough for you to pronounce the Shahaadatayn (the declaration of faith) and start to practise the rituals of Islamic worship, such as prayer and following what is commanded by Allaah and His Messenger. We ask Allaah to pour His blessings on you and to guide you to the straight path.
