Salaam.
For one lesson, the Prophet ﷺ pointed to nothing grander than a bird.
لَوْ أَنَّكُمْ كُنْتُمْ تَوَكَّلُونَ عَلَى اللَّهِ حَقَّ تَوَكُّلِهِ لَرُزِقْتُمْ كَمَا تُرْزَقُ الطَّيْرُ تَغْدُو خِمَاصًا وَتَرُوحُ بِطَانًا
Law annakum kuntum tawakkalūna ʿalā Allāhi ḥaqqa tawakkulihi la-ruziqtum kamā turzaqu aṭ-ṭayru taghdū khimāṣan wa tarūḥu biṭānan.
"If you were to rely upon Allah with the required reliance, then He would provide for you just as a bird is provided for: it goes out in the morning empty, and returns full." — the Prophet ﷺ, narrated by ʿUmar ibn al-Khaṭṭāb (RA) · Jāmiʿ at-Tirmidhī 2344 (ḥasan ṣaḥīḥ)
The bird doesn't wait for the food to be in front of it. It leaves anyway — into a day whose shape isn't set yet, with nothing in hand. That's the part worth sitting with: not the full belly at the end, but the empty one at the start, and the leaving that happens regardless. You know that leaving — stepping into the conversation, the meeting, the drive home, before anyone's told you how it goes. The bird leaves empty. Its provision is with Allah, and it goes out all the same. We try to leave only once we're sure. The hadith points the other way: not to certainty about the day, but to Whose hands it's already in.
O Allah, when I have to step into what I can't yet see, let me go the way the bird goes — trusting You with the day.
