The tactic that that i see is the
Makkan and Madani period technique, the Messenger of Allaah (peace be upon him) taught them how to love Allaah, His Messenger, the truthfulness of the hereafter, judgement day, paradise, hellfire, within Makkah, it made them love the deen and get attatched. It changed their inside - softened their heart, and once they were firm on the deen and whole heartedly into it - the major commandments of the halaals/haraams came within the Medinan Period.
So using wisdom, we
gota make them love Islaam. Most think it's just a basic set of rules, but in reality these are a blessing. So we give them
heart-softeners first, we explain to them the reality of Islaam and gradually help them make salaah. Once they become used to this, then they are prepared to change their lifestyle.
Ask any person who's become practising whole-heartedly, and you'll realise they went through a
gradual process. I.e. if you go upto someone and say "THAT'S HARAAM, YOU FAASIQ/SINNER!" they going to distance themselves from you right?
And by the Mercy of Allah, you dealt with them gently. And had you been severe and harsh*hearted, they would have broken away from about you; so pass over (their faults), and ask (Allah's) Forgiveness for them; and consult them in the affairs. Then when you have taken a decision, put your trust in Allah, certainly, Allah loves those who put their trust (in Him).
[Qur'an 3: 159]
Don't you know that the majority of the Jews obeyed Allaah out of excessive fear? The christians became misguided and had excessive hope and love to the effect they turned away from their book? But the Muslims are in between - hope, fear, love which is balanced.
We are the balanced ummah.
So
use your wisdom. Treat these brothers and sisters like new reverts, teach them the basics because many don't know them. They have questions but they think they're not allowed to ask.
Instill the love of Allaah, His Messenger and show them you care, and that's why you don't want them to do wrong - because sinful acts are forbidden so they don't harm us.
Show them the harms of that bad and the benefits of the good, and be patient with them.. sometimes you need to be gradual and patient, because they may be changing inside, they just waiting for the right time to change. If they jump into it in one go - then they likely to jump out the exact same way. But if they enter gradually, then they are likely to remain firm on it and change aspects of themselves gradually so they don't overburden themselves.
I had a friend in high school who never knew how to pray, atleast i think he never. What used to happen is that when we prayed Jummuah, he used to just do the movements without saying the words i think. The mates would laugh at him for not knowing how to pray - would that bring him closer to Allaah? No.
When we went college, we had many friends who had started practising Islaam. He started joining in because he felt the odd one out. He would be taught in kindness, because we want to bring him closer to Islaam - not distance him. So why embarrass him if our main intention is to draw him closer to Allaah? Rather we make him comfortable with us so if he is unsure of anything - he can ask and we can tell him that it's nothing embarrassing, and he will feel happy that he has mates who care.
The Messenger of Allaah treated the people with honor, even if someone was a high class or low class person - so the man would feel proud of being muslim and getting that respect. That's what you want to give other people.
Don't feel your better than this person, because it might be that you die in an evil state (we seek refuge in Allaah), and it might be that this person dies in the state of Islaam. So always be humble yet honorable;
And the true servants of the Most Merciful are those who walk the earth with humility and when the ignorant address them, they respond with words of peace.
[Qur'an 25:63.]
16:125 Call unto the way of your Lord with wisdom and beautiful preaching and reason with them in the best manner. Verily your Lord knows best who has strayed from His path and and best knows He as to who are the rightly-guided.
41:34 The good deed and the evil deed cannot be not equal. Return an evil deed with one that is good. Then he between whom and thyself was mutual enmity shall become as though he were an intimate friend.
And Allaah knows best.
