Being happy doesn’t mean everything is perfect, it just means that you’ve decided to look beyond life & Trust Allah!
The Prophet (pbuh) said: “How wonderful is the situation of the believer, for all his affairs are good. If something good happens to him, he gives thanks for it and that is good for him; if something bad happens to him, he bears it with patience, and that is good for him. This does not apply to anyone but the believer.” (Narrated by Muslim, no. 2999).
