na tha kuch to khuda tha | نہ تھا کچھ تو خدا تھا | न था कुछ तो ख़ुदा था

na tha kuch to khuda tha, kuch na hota to khuda hota
duboya mujhko hone ne, na hota main to kya hota


hua jab ghum se yu bebas, to ghum kya sar ke katne ka
na hota agar juda tan se, to jaano par dhara hota


huyi muddat ke gaalib mar gaya par yaad aata hai
wo har ek baat per kahna ke yu hota to kya hota


na tha kuch to khuda tha, kuch na hota to khuda hota
duboya mujhko hone ne, na hota main to kya hota




نہ تھا کچھ تو خدا تھا, کچھ نہ ہوتا تو خدا ہوتا 
ڈبویا مجھکو ہونے نے, نہ ہوتا میں تو کیا ہوتا 


ہوا جب گھوم سے یوں بےبس, تو گھوم کیا سر کے کاٹنے 
نہ ہوتا اگر جدا تن سے, تو جانو پر دہرا ہوتا 


ہویی مدّت کے گالب مر گیا پر یاد آتا ہے
 وہ ہر ایک بات پر کہنا کے یوں ہوتا تو کیا ہوتا 


نہ تھا کچھ تو خدا تھا, کچھ نہ ہوتا تو خدا ہوتا 
ڈبویا مجھکو ہونے نے, نہ ہوتا میں تو کیا ہوتا 




न था कुछ तो ख़ुदा था, कुछ न होता तो ख़ुदा होता
डुबोया मुझ को होने ने, न होता मैं तो क्या होता


हुआ जो ग़म से यूँ बेहिस तो ग़म क्या सर के कटने का
न होता गर जुदा तन से तो जानूं पर धरा होता


हुई मुद्दत के ग़ालिब मर गया पर याद आता है
वह हर एक बात पर यह कहना के यूँ होता तो क्या होता


न था कुछ तो ख़ुदा था, कुछ न होता तो ख़ुदा होता
डुबोया मुझ को होने ने, न होता मैं तो क्या होता

Concept of ordered set

Any set S with a relation, say less than equal(<=) to is said to be ordered if for any two elements X and Y of S, either X<= Y or Y <= X is true. Then we may also say (S, <=) is an ordered set.

We know given two integer, say N1 and N2, we can always say whether N1<=N2 and N2 <=N1. Similarly if you are given two rational numbers or the real numbers, say N1 and N2, then it is always possible to tell whether N1 <= N2 or N2 <= N1.

Pattern of ordered set: An ordered set of numbers or objects; the order helps you predict what will come next, because this order follow a pattern unit to generate a set/list. 

Pattern unit: The part of a pattern that repeats.
