Mahmood Khan - Rukna Mumkin Nahi

Can someone translate this song? I´d like to make a video subtitled in Spanish, though I don´t know if I´ll be allowed to put this video in Youtube.

kaisa ye zamana dil ko meyrey jachta nahi
kia he din ka kerna mei yahan hoon tu hai kaheen
yahan jub bhi zikar ho tera ho basney walon ki roshni
yahan sub geeton ki lehrein terey aangan mei hai chupi huee
jitna bhi ho sakey mei terey sang rehna
terey anay sey pehley mey nay hur gum hans kai sehna
meyree nao kinarey
phir se tu laga dey

sarey aasamano kai in lafzon per
tu phir sey likh dey meyrey saawan jaisey in hathon per
tu kuch na mumkin he nahin
mera sab kuch terey damn se he tu

hai meyrey aankein bhari terey aaney per
iss dil ko kaisey mei behlaoon terey gum janey per
zara runkna mumkin he nahi
mera sab kuch terey damn se hee tu hai

do saathe akilay duniya mei ho koyee nahi
dey ker sab kuch apna bas mil jaoon mein tujh mei kahaan
jitna bhi chahey yun mujehy tu aazmana
miley na he tamana mei ney bilkul na ghabrana
mera her ye irada
mujhey jaan se piyara

sarey aasamano kai in lafzon per
tu phir sey likh dey meyrey saawan jaisey in hathon per
tu kuch na mumkin he nahin
mera sab kuch terey damn se he tu
hai meyrey aankein bhari terey aaney per
iss dil ko kaisey mei behlaoon terey gum janey per
zara runkna mumkin he nahi
mera sab kuch terey damn
se hee tu hai
