71. Nuh/Prophet Noah
I/We begin by the Blessed Name of Allah
The Immensely Merciful to all, The Infinitely Compassionate to everyone.
71:01
a. Truly, WE assigned Noah with a Divine Mission to his people, saying:
b. ‘Warn your people of the consequences of disobedience to the Divine Message before a grievous punishment would actually afflict them!’
71:02
a. Thus he proclaimed:
b. ‘O My People!
c. I have been assigned to you as a Clear Warner and my message is simple to understand and easy to follow.
71:03
a. The message is:
b. ‘Submit in worship and reverence to Allah alone, and
c. fear HIS disobedience and be reverent to HIM,
d. and, thus, follow me’ in guidance.
71:04
a. By so doing, ‘HE will be forgiving some of your past sinful offenses, and grant you respite till an appointed time - the time of death – instead of destroying you immediately.
b. But when Allah’s Appointed Time will come, then it would neither be averted nor delayed, if only you knew.’
71:05
a. So Noah spent hundreds of years conveying the Divine Message but he faced immense opposition, insult, and mockery.
b. Thus he submitted:
c. O ‘My Rabb - The Lord!
d. Truly, I have appealed to my people by night and by day, as I was assigned to do,
71:06
a. but the more I would call, the farther they would run away’ from my advocacy.
71:07
a. And, truly, each time I would call them so that they would accept The Truth and YOU may
thus grant forgiveness to them,

A novel technique for conversion of DC power to AC power is introduced using solar powered sine wave generation system is presented. DC power extracted from solar system is made utilitarian for driving the BLDC (brushless DC) motor with constant speed constraints. The back EMF signals of each phase of the BLDC motor facilitated the development of technique for the sine wave generation from solar system without battery backup. This motor is coupled with AC generator, which yields the AC power on demand. The constant speed constraint indispensable for fixed electrical frequency at the output of generator. A new control technique is rendered for reference tracking speed control of BLDC motor using Lyapunov theory by changing switching frequency, and also maintaining the voltage level at the output of converter driving BLDC by regulating the switching frequency of the zeta converter. The proposed methodology for generation of AC power from solar power system is also tested on prototype. The comparison of conventional technique for generation of sine wave power and proposed scheme is mentioned at later section of this paper for describing the efficacy of newly presented scheme.
Extensive field surveys were conducted to collect Pierid butterflies and their host plant flora from all districts (Jhelum, Rawalpindi, Chakwal, Attock, and Islamabad) of Potohar region of Punjab Pakistan during January 2012 – February 2015. A total of 1839 specimens belonging to 19 species were identified under two subfamilies and ten genera. The identified species were Catopsilia pyranthe, C. crocale, C. pomona, Gonepteryx mahaguru, G.rhamni, Colias fieldii, C. erate, Eurema laeta, E. hecbae, Delias eucharis, Pontia daplidice, Belenois aurota, Pieris rapae, P. canidia, P. brassicae, Ixias pyrene, Colotis amata, C. etrida, and C. protactus. Among these, eight (08) species; Delias eucharis, Belenois aurota, Pieris rapae, Colotis amata, C. etrida, Gonepteryx mahaguru,G.rhamni and Colias erate were reported for the first time from Potohar region. The current study as being first biogeograhical study from Potohar region recognizes the elements from all biogeographical regions of the world. However, the Afrotropical and the Aust- oriental elements remain dominant. Among reported host plants, 21 species of 15 plants [Capparis aphylla, (family Capparaceae), Cassia fistula, Sesbania grandiflora (family Fabaceae), Salvadora oleoide (family Salvadoraceae), Loranthus longiflorus, Scurrula pulverulenta, (family Loranthaceae), Rhamnus triquetra, R. purpurea (family Rhamnaceae), Brassica napus, B. oleraceae, B. oleraceae var. italica, B. campestris, B. officinalis, Raphanus sativus, Eruca sativa (family Cruciferae)] are new records for Pakistan, However six (06) host plants [Lepidium pinnatifidium, Coronopus didymus, Arabidopsis thaliana (family Cruciferae), Cassia occidentalis, Medicago sativa, and Melilotus officinalis (family Fabacae)] are new addition to world''s host plant list of Pierids fauna. GIS map distribution of all the butterflies along with their host plants is provided for the first time from pakistan.Taxonomic keys for subfamilies, genera and species were also prepared. From the study area, the complete list of host plants of family Pieridae up to species level has been provided first time. In the present study, relative abundance and percentage of different butterflies were found in each district. In district Jhelum, Pieris brassicae showed highest relative abundance (0.18) and percentage (18.12), with its host plant Brassica oleraceae (0.25) and percentage (25) respectively. In district Rawalpindi, xvii Pontia daplidice showed highest relative abundance (0.20) and percentage (20.05) with its host plant Lepidium pinnatifidium (0.28) and percentage (28). In the districts Attock and Chakwal, Catopsilia pomona showed highest relative abundance (0.19) and percentage (18.99) with host plant Coronopus didymus (0.38) and percentage (38) and Lepidium pinnatifidium, Brassica napus, Brassica compestris (0.16) and percentage (16). In district Islamabad, Pieris canidia showed highest relative abundance (0.23) and percentage (23.22) with its host plant Coronopus didymus (0.28) and percentage (28). Diversity of Pierids butterflies and their host plants was calculated by using five diversity indices namely; Simpson, Shannon, Evenness, Menhinick, Margalef and Equitability. The values from five districts of Potohar region were within suitable range of Simpson index i.e. between 0.8-0.9 for butterflies species and host plant which shows their stable community in the region. However, Shannon and Weiner values of five districts revealed that Potohar region has rich host plant flora and butterfly fauna with even distribution as most of values were between 1.8 and 2.4. In Potohar region, the values of evenness index ranges between 0.5-0.8 which shows even distribution of butterfly''s species and host plants in the region. The overall calculated values of Menhinick index of butterfly''s species were between 0.5- 0.7 which showed high diversity of butterfly''s species and host plants within the region. The Margalef and equitable index values showed high species richness for butterflies and host plants in the region. Highest species richness were recorded in Rawalpindi and Islamabad districts (2.336-2.023) and comparatively low species richness were recorded in district Attock (1.516) and for the host plants highest specie richness were recorded in the same 2 districts i.e. 1.83 and in Rawalpindi and Islamabad.
