Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

 

1- Fajr prayer is when morning light in the sky starts spreading horizontally.

 

Sunrise is when the top of the sun’s disk just appears above the horizon.

 

Zhuhr is when the sun begins to decline after reaching its highest point in the sky. So the term Zawal means the beginning of the movement of the sun from that point.

 

Asr is when the length of any object’s shadow reaches the length of the object itself. Hanafi School says twice in length.

Maghreb or Sunset is when the top of the sun’s disk just disappears below the horizon.

Isha is when the (Shafaq) redness or whiteness from sky disappears.

 

2- If it is sitting there with no use at all, no Zakat is applicable on it. Only if you plan to sell it then you pay Zakat on that money 2.5% of that amount once every year.

 

Almighty Allah knows best.
