It is not a good thing that Quran is playing in background and you are busy in your own work. As courageneverdies mentioned Quranic verse:
7:204 When the Qur'an is read, listen to it with attention, and hold your peace: that ye may receive Mercy.
So as Allah says that we should listen Quran attentively. Beside this there are Ayats of Sajda in Quran. When we listen those Ayats then Sajda becomes Farz for us. Ab hm ma sy sb Hafiz-e-Quran tu nhi hy, hmain kis trah pata lgy ga k Sajday wali Ayat parhi ja rhi hy. Tu is ka gunah hmaray sir
pr hi ho ga.
Second baat ye hy k Quran sun-nay sy ziada Quran parhnay ka ziada sawab hy. Agr hm daily kuch time nikaal kr Quran ko samjh kr parh lein tu is ka hmain boht faida ho ga. Aik Hadees ka mafhoom hy:
"Quran k hr Harf k badlay 10 naikyaan milti hein"
Jb hm Quran parhain gy tu usy parhnay ka sawab alag milay ga aur agr Allah ny Taufeeq di tu usy samajh kr ammal krnay ka be-hisaab sawab alag milay ga.
Is liay meray khayal mein hmein Quran sun-nay ki bajaey usay parhnay ki aadat apnani chahiay hy. Jo time hm Quran sun-nay k liay nikaltay hein, us sy b half time main agr hm wuzu kr k Quran thora parh lein tu hm boht faiday mein rhein gy.
