If we want to do things for the sake of Allah, we must be prepared to sacrifice. We don't work alone anymore, but in a jamaah. We don't do things our way, but carry out decisions that are collectively agreed upon. We need to be patient to accept all kinds of personalities.
We need humility and wisdom to carry out discussions. When we refuse to discuss or fail to communicate with one another, then we're not doing it for the sake of Allah. This is the wisdom taught to us by the Prophet (pbuh). So the next time we say "we're doing this for the sake of Allah", ask ourselves: Have we really given in to humility or have we let our desires get the better of us? So let's not just pay lip service. If it is for Allah's sake, then forsake personal feelings and work to have the wisdom to rise over the petty and the small stuff.
Witnessing the weakness of others is not a reason for us to gossip, but to remind us that there are still among us who are struggling to become better, and it is for the strong to guide them with wisdom and gentle reminders.
We always want things to go our way. Or do things the way we want to do it. When they don't, have we forgotten that Allah is the Best of Planners? He's using us as His instrument to do good the way that only He knows best. So don't sulk or throw a fit. Go with the flow.
Syawwal is a time of reflection. Eid ul Fitr was about returning to our fitrah. We started life good, but along the way our fitrah got corrupted. Now's the time to purify our mind so that only knowledge that's constructive and positive come to you. Now's the time to purify our body and spirit, to show that just as we were in control of ourselves in Ramadhan -- reining in our anger, our desire, and so forth -- so will we continue to be from this day forward.
