A piece of advice from the heart of a humble and sinful servant, perhaps it will reach the heart of a pure servant striving for righteousness:
Before you engage in any action, think: "Would the Prophet ﷺ, and his companions or the female companions have done this action?" If the answer is yes, then rely on Allah and go ahead, and if the answer is otherwise, seek refuge from Shaytan, fear your Lord, and reconsider.
Do not make excuses for yourself, for there is no benefit in disobeying Allah, as Shaykh al-Islam Ibn Taymiyyah رحمه الله said: "Evils, both apparent and hidden, contain no benefit."
Preserve your knowledge and dignity from perishing, for sins diminish prestige, light, and beneficial knowledge.
Avoid disputes and conflicts, for they bring sorrow and sadness. The company of the righteous is a blessing, so preserve your friend and do not let Shaytan divide you. Do not let women come between you and your male friends, and do not let men get between you and your female friends, for gatherings where haram love and flirtation are mentioned are gatherings of Shaytan.
Do not accept for any muslim what you would not accept for yourself.
If your Salah doesn’t stop you from sin, then check it and improve it.
If you stray from the path, hasten to repentance and seeking forgiveness, and remember that good deeds erase bad deeds. Conceal your sins if you have sinned, and do not expose yourself after Allah has concealed you
If you are afflicted [with sin] then conceal it.
Rush towards goodness and do not be saddened by the blame of blamers. Fear only Allah and do not fear the wrongdoers, you will be in your grave alone.
Always! Expect the best from your muslim brothers and sisters, and communicate with them, don’t let your assumptions [which are a mere illusion] guide your actions [which are a reality].
Forgive and forget, have a heart like those mentioned in the hadith: “hearts like those of birds”.
Do not let your mercy affect your judgment in serious situations, look at everything from a shar’i perspective, if something is against the shar’, abandon it even if everyone will be hurt. And never say “my intention is pure I am just intending to please a fellow muslim”… the result does not justify the action.
Be mindless when it comes to expecting well from Allah, be illogical, Allah Himself is not “logical”, His decree was never understood by logic or science, it’s all miracle after miracle, so expect the best and remember to entrust your affairs to Allah alone and not the means you take [obviously take your means but don’t rely on them alone]
Remember that this dunyah is either a bridge to jannah or Jahannam, not a place of joy and fun. So do that which will take you to Jannah, even if your entire dunyah life may go to waste. Trade with Allah, the greatest the sacrifice the bigger the reward.
May Allah bless you and increase you in closeness to Him. All praise is due to Allah, the Lord of all worlds."
