گھگھی تے پیسے

گھگھی تے پیسے

اک واری دی گل اے کہ اک ٹاہلی اتے اک گھگھی نے آہلنا پایا ہویا سی۔ اوس نے انڈے دتے جنہاں وچوں دو بہت ای سوہنے بچے نکلے۔ گھگھی بہت خوش سی۔ اوہ بچیاں لئی کول دے کھیتاں وچوں دانے اکٹھے کر کے لیاندی۔ انج کئی دن ہو گئے۔ ہن اوہدے بچے کجھ سیانے ہو گئے سن۔

اک دن اوس نوں کسے تھاں توں پیسیاں والی پوٹلی لبھی۔ اوس ایہہ پیسے اپنے آہلنے وچ لیا کے رکھ دتے۔ اک دن پنڈ دا اک منڈا گھگھی دے بچے آہلنے وچوں کڈھن لئی درخت اتے چڑھیا۔ اوس نوں پیسیاں والی پوتلی نظر آئی۔ اوس پوٹلی چکی تے تھلے اتر آیا۔ جدوں گھگھی واپس آئی تاں اوہ پوٹلی اوس نوں نظر نہ آئی تاں اوہ آکھدی اے کہ ’’کوگوں کوں کوئی بھکھا مار دا میرے پیسے لے گیا۔‘‘ اوہ منڈا تھلے کھڑا گھگھی دی ساری گل بات سن رہیا ہوندا اے۔ اوہدی گل سن کے اوس نوں بہت غصہ آندا اے۔ اوس اک وتا چک کے گھگھی دے ماریا جو اوہدے سر وچ لگا تے اوہدا سر پاٹ گیا۔ اوہ آکھدی اے کہ ’’کوگوں کوں، اسیں لال پراندے پائے نیں‘‘ اوہدا زخم ٹھیک نئیں ہوندا۔ اوہدے وچ کیڑے پے جاندے نیں تے اخیر اوہ مر جاندی اے۔ فیر اوس نوں نہوا کے کفن پایا جادنا اے تے دفن کر دتا جادنا اے۔

علم مختلف الحدیث پر امام شافعی کے تفکرات کا تحقیقی مطالعہ

After the era of Prophet Muhammad (S.A.W), there were dissimilarities in interpretations of contradictive revelations by Muhammad (S.A.W) thereby questioning their authentication while being considered a basic source of extracting the Sharia acts. In this context, Imam Shāfʿī studies all the dissimilarities and contradictions and devised finest principles which performed very positive role in rationalizing the conflicting Ahadiths. He was first to discuss these matters in an innovative manner. It is therefore, essential for investigator to refer to Shāfʿīs principles to rationalize any Hadith lying under contradiction. Imam Shāfʿī stated that Hadith is not itself contradicting but its apparent meaning leads the investigator into misconception. Consequently, he has stated three methods to remove this conflict. First is the combination (جمع) which recommends working on both Ahadiths at the same time rather than leaving either of them. Second is the abrogation (تنسیخ) which requires extensive knowledge of Quran and History before inferring the final decision of Muhammad (S.A.W) and scholars widely recommend Imam Shāfiʿī in recognizing abrogated Ahadiths. Third is preference (ترجيح) which is based upon peripheral attributes.

An Analysis of Effectiveness of Extension Work Conducted under Farmers Field School Ffs Approach for Sustainable Agricultural Development in the Punjab, Pakistan

Agriculture is vital for Pakistan''s economy. Whatever happens to agriculture is bound to affect not only the country’s growth performance but a large segment of the country’s population as well. The development of agriculture depends on many factors including agricultural extension as an institutional component. Since independence many extension approaches have been tried from time to time but met with partial success in increasing farm productivity. Recently, government of Punjab has introduced a new extension approach known as farmers field school (FFS) in 15 districts of province. But, how do farmers view its effectiveness in meeting their needs is the forehand question which needs to be answered. Keeping this in view, the present study was designed and conducted in the randomly selected three districts under FFS. A multi-stage sampling technique was used for the selection of sample from study districts. Three districts were selected randomly, and then one tehsil from each randomly selected district was taken randomly, the randomly selected tehsils were Sargodha, Sheikupura and mailsy, from fruit, vegetables and cotton areas respectively. A sample of 341 respondents from the population of 3000 registered FFS farmers were taken randomly. The sample size was determined by using table developed by Fitzgibbon et al (1987). Data were collected through an interview schedule, and data obtained were statistically analyzed by using computer software i.e. SPSS. According to the data, 36.4% respondents were of age 41 years and above. Only 14.67% respondents were illiterate, a simple majority (53.1%) of the respondents had less than 12.5 acres land holding and 88% respondents were owner. Majority (65.1%) of the respondents'' source of income was only farming and 37.5% respondents had annual income less than Rs.100000. All the respondents were acquainted with the FFS staff, and regarding acquaintance with qualities of FFS staff, dutifulness gained the weighted score 1168 and was ranked at top, similarly regarding acquaintance with the duties of FFS staff and responsibilities of FFS member farmers, the duty "to coordinate all FFS personnel" gained a weighted score 1174 and responsibility "To roll call in the end of FFS meeting" gained a weighted score 1131 and were ranked at top, respectively. Overwhelming a majority (82.40%) of respondents were of the view that FFS staff had weekly contact with them. Similarly 71.6, 79.8, 88.6, 61.6, and 64.8% respondents reported that the FFS was 1-square distance from their home, situated at a central place, established at Dera, selected with mutual consultation of farmers and conducted on a need based survey, respectively, whereas 79.18% respondent''s source of information was fellow farmers. Information provided about fertilizer requirement gained a weighted score 1086 and was ranked at the top, and regarding effectiveness, the information about hoeing was ranked at the top with a weighted score 1207 and majority(57.42%) of the respondents reported that "special topic/hot issue" was performed in the FFS to an average extent. Similarly, 63.58% and 58.6% respondents were of the view that the group discussion method was used and effective to an average extent and was ranked at the top with a weighted score 1107 and 1128, respectively. It was also concluded that during the use of different extension methods the pre-requisites of each extension method were used to below an average extent. Similarly FFS material was provided to below an average extent, whereas 41.31% of the respondents considered the lead pencil as effective to an average extent. An AESA/CESA activity like "farmers are properly briefed before field activity" was ranked at the top with weighted score 1081 and was performed to an average extent. There existed significant association of age with qualities of FFS staff, use of extension methods by FFS staff, responsibilities of FFS member farmers and effectiveness of information provided by FFS staff. Size of land holding had highly significant negative association with qualities of FFS staff and responsibilities of FFS member farmers. Annual income of respondents had also highly a significant positive association with qualities of FFS staff, whereas there existed highly significant positive association of education with qualities of FFS staff, use of extension methods by FFS staff, responsibilities of FFS member farmers and effectiveness of information provided by FFS staff.
